The Prince of Wales has revealed the five winners of this year's environmental Earthshot Prize, calling them an "inspiration that gives us courage".

Prince William said their work was "proof that progress is possible" during Wednesday evening's awards ceremony in Rio de Janeiro's Museum of Tomorrow.

Winners include a project for making South America's Atlantic Forest financially viable and a global ocean treaty initiative aimed at conserving marine life.

Brazilian football legend Cafu, Olympic gymnast Rebeca Andrade and former Formula 1 driver Sebastian Vettel were among the award presenters.

Performances from Kylie Minogue, Shawn Mendes and Brazilian queen of pop Anitta also got the jubilant mood swinging.

Earthshot Prize supports eco-friendly projects from around the world, and annually awards each of the five winners with a £1m grant to scale up their ideas aimed at repairing the world's climate.

Organisers of the initiative were inspired by former US President John F Kennedy's Moonshot project, which challenged scientists to get astronauts to the Moon and back safely.

Hosted by award-winning Brazilian broadcaster Luciano Huck, the awards ceremony was addressed by Prince William, the Earthshot Prize's president.

"When I founded the Earthshot Prize in 2020, we had a 10-year goal: to make this the decade in which we transformed our world for the better," he told attendees.

"We set out to tackle environmental issues head on and make real, lasting changes that would protect life on Earth."

There are five Earthshots or goals: Protect and Restore Nature; Clean Our Air; Revive Our Oceans; Build a Waste-free World; and Fix Our Climate.

The future king has committed himself to it for 10 years, with Rio marking a halfway point for the venture.

This year saw nearly 2,500 nominees submitted from 72 countries. Out of them, 15 finalists were selected, from which the five winners were chosen.

Earthshot Prize 2025 - Full list of winners

• Protect and Restore Nature: re.green, in Brazil, is making protecting one of the world's most important ecosystems, the Atlantic Forest, financially viable
• Clean Our Air: The city of Bogotá, has shown how public policy can bring lasting change, through means such as clean air zones and re-greening degraded areas in the Colombian capital
• Revive Our Oceans: The High Seas Treaty is a global ocean initiative that will set out clear measures to conserve marine life, among other things, and will go into effect from January 2026
• Build a Waste-Free World: Lagos Fashion Week, in Nigeria, is redefining the industry, with each designer wishing to showcase required to show their commitment to sustainable practice
• Fix Our Climate: Friendship is dedicated to helping vulnerable communities across Bangladesh for a multiude of things from access to public services, health, education and preparing for natural disasters

Referring to the winners as "innovators", Prince William called the Earthshot Prize a "mission driven by the kind of extraordinary optimism we have felt here tonight".

"There's a great deal we can learn from their determination, their vision for scale, and their unyielding belief that we can create a better world."

The chair of the board of trustees, Christiana Figueres, said they were building a "global legacy".

"These winners are proof that the spirit of collective action born here in Rio continues to grow stronger, more determined, and more urgent than ever.

"Their 2030 aims are deeply ambitious - but their impact to date, their plans in place and their tenacity fuels my optimism."

Earlier in the day, Prince William met the 15 finalists during a visit to the Christ the Redeemer statue, where he posed for a photograph on the same spot his late mother, Diana, Princess of Wales, did 34 years ago.

But much of the prince's five-day visit to Brazil has been focused on climate and the environment.

On Tuesday, he criticised criminals for their involvment in the deforestation of the Amazon rainforest during a speech at the United for Wildlife conference.

He also travelled to the small island of Paqueta, where he met locals, learnt about mangrove conservation and planted tree saplings.

On Thursday, he will be travelling to Belem in the Amazon rainforest, where he is scheduled to give a speech at COP30, the UN's annual climate change meeting.

If you've ever wanted to create your own computer program but never learnt how to code, you might try "vibe coding".

Collins Dictionary's word of the year - which is confusingly made up of two words - is the art of making an app or website by describing it to artificial intelligence (AI) rather than by writing programming code manually.

The term was coined in February by OpenAI co-founder Andrej Karpathy, who came up with the name to represent how AI can let some programmers "forget that the code even exists" and "give in to the vibes" while making a computer program.

It was one of 10 words on a shortlist to reflect the mood, language and preoccupations of 2025.

By giving an AI tool a simple description such as "make me a program that schedules my weekly meals", people can use "vibe coding" to make basic apps without any previous programming knowledge.

More complicated tools still require skill, but the practice has opened up creating digital platforms to non-coders.

As many have discovered, it isn't perfect - with no guarantee the code will actually work or be free of bugs.

Alex Beecroft, the Managing Director of Collins, said the term "perfectly captures how language is evolving alongside technology".

'Clankers' and 'broligarchy'

Not all the words necessarily first emerged in 2025 - but Collins decided this was the year they became popular.

For example "clanker", a term used to describe robots in Star Wars games and movies since the mid 2000s, made the list after it went viral on TikTok in July as people shared their frustrations with AI-powered machines.

While "aura farming" - people doing things for the sake of looking cool, often when they know they're being filmed - was first used in January 2024, but became increasingly popular over the course of 2025.

And the portmanteau "broligarchy" took off in 2024 to describe the owners of the world's biggest technology companies and their purported political influence - and was used frequently in 2025 following the appearance of many of the bosses at US President Donald Trump's inauguration.

The other definitions in the shortlist were:

• Biohacking, the activity of altering the natural processes of one's body in an attempt to improve one's health and longevity

• Coolcation, a holiday in a place with a cool climate

• Glaze, to praise or flatter someone excessively or undeservedly

• Henry, acronym for "high earner, not rich yet", or a person who has not accrued substantial wealth from their high income

• Micro-retirement, a break taken between periods of employment in order to pursue personal interests

• Taskmasking, the act of giving a false impression that one is being productive in the workplace

Headaches are something almost all of us deal with at some point.

They can last from a couple of minutes to days and the pain can be sharp, dull, throbbing or stabbing and sometimes spread beyond your head to your scalp, face or even your neck.

Dr Xand van Tulleken, who hosts the BBC's What's Up Docs wellness podcast, knows the feeling all too well and says he gets headaches once a month or every six weeks and it "feels like someone's drilling into my eyeball".

While it's easy to panic about what might be behind a bad headache, Dr Katy Munro, a GP and expert at the National Migraine Centre, says it's rarely something serious.

"It's natural to worry that something is seriously wrong, but the chances of that are actually very small," she explains.

She advises that if it's your "first or worst headache, get it checked out by a doctor," but if you're getting a pattern of milder, recurring headaches, there are a few simple things you can try at home as well as seeing your GP.

1. How big was the impact on your day?

Dr Xand says understanding your own headaches can be surprisingly helpful as they often don't have a single cause so keeping a diary can help you spot patterns and triggers.

For some people, weather such as thunder and lightning could trigger it, while for others it might be sensitivity to light.

"The worst time for me is when we're driving in the autumn and the sun is low and the sun is flickering through the trees...it really aggravates," says Dr Munro.

It's worth noting down things like:

• What you were doing when the headache started
• What you ate or drank
• How well you slept
• The weather
• For women, track your menstrual cycle, as headaches can be linked to hormonal changes

But, Dr Munro cautions that you shouldn't overdo it.

"I made the mistake of making mine very detailed, which was depressing. Instead keep it simple and maybe write a number from one to 10 to summarise the impact it had on your day.

"It's also useful to track how many crystal-clear days you have, not just the bad ones.

Your doctor can then review it to help identify patterns.

2. Use caffeine wisely

You might think that caffeine is something you should instantly avoid if you have a headache but Dr Munro says the truth is more nuanced.

In small, careful doses, it can make painkillers more effective if you are not having too much caffeine on a daily basis.

"Caffeine is a co-analgesic which means it can boost the effect of a painkiller," Dr Munro explains, but avoid it in the afternoon and evening as it can disrupt your sleep.

It's worth also thinking about your caffeine consumption more broadly - consuming lots of it every day can cause a caffeine overuse headache and if you suddenly stop, you might get a withdrawal headache.

3. Don't skip meals

What you eat and when may make a difference if you're suffering from headaches.

Dr Munro recommends following a diet similar to the Mediterranean one that is rich in protein, healthy fats and complex carbs which can help stabilise your energy levels.

You should avoid quick-release sugary snacks and definitely don't skip meals as that can be a common trigger.

Dr Munro says she found her headaches were helped by cutting out dairy and gluten, though that's not universal.

"I also found eating regularly and taking lunch to work made a difference," she says.

As well as thinking about food, Dr Munro says regular exercise, good sleep, stress management and staying hydrated can also help reduce headaches.

You should drink enough during the day so your pee is a pale clear colour and you don't feel thirsty.

4. Avoid painkillers with codeine

"There are lots of things, like painkillers or anti-nausea tablets, you can buy over the counter that may be helpful to manage headaches" says Dr Munro.

She cautions that you should avoid "anything containing codeine" as it can make some headaches occur more frequently and can worsen symptoms like nausea.

"Painkillers can work extremely well but it does depend on how severe your headache is.

"If they're becoming more frequent or intense, your GP can help you find a more suitable medication."

Make sure you don't regularly take painkillers on more than two days a week as this will reduce your risk of rebound headaches.

It is always perilous for a government when it clearly lacks grip on an issue voters would reasonably expect it to be in control of.

The stand out example of this in recent years has been the arrival of migrants on small boats.

From Rishi Sunak's promise to "stop the boats" to Sir Keir Starmer's promise to "smash the gangs" both have been found wanting and the problem remains huge.

Now the government confronts another example: a justice system that is palpably, transparently and repeatedly failing – and where measures designed to address the issue of letting prisoners out by accident aren't working.

According to government figures published in July, 262 prisoners were released in error in the year to March of this year - a 128% increase on 115 in the previous 12 months.

In other words, it has been a problem for some time, and it is getting worse.

And, context is everything in politics: this row now comes after the mistaken release of perhaps the most high-profile prisoner jailed this year.

Hadush Kebatu, who arrived in the UK on a small boat, was jailed after sexually assaulting a 14-year-old girl and a woman while living in an asylum hotel in Epping in Essex, only to be let out by accident. He has since been deported.

It gave the issue of accidental releases from prison a salience and prominence it hadn't had until then.

Once again, we are seeing ministers use the language we usually see from opposition politicians.

The Home Secretary Shabana Mahmood has described the number of people arriving on small boats as "shameful".

Now, the Deputy Prime Minister and Justice Secretary David Lammy is saying he is "absolutely outraged" over the mistaken release a week ago of Brahim Kaddour-Cherif, a 24-year-old Algerian sex offender.

Lammy added that his officials have been "working through the night to take him back to prison."

Which brings us to the messy genesis of this saga, at B-Team Prime Minister's Question Time on Wednesday lunchtime.

With the prime minister at the COP climate summit in Brazil, it was his deputy who was answering questions.

The Conservatives put up the shadow defence secretary James Cartlidge, who repeated a question, using a very particular form of words, over and over again.

He wanted to know if an "asylum-seeking offender had been accidentally released from prison".

It was obvious from the Press Gallery that Cartlidge was on to something – because of the apparent precision of his language and his constant repetition of the question.

But Lammy chose to repeatedly duck the question, despite, we later learnt, knowing about the case Cartlidge was referring to.

So why didn't he address it?

It turns out Cartlidge had got his facts wrong - Kaddour-Cherif isn't an asylum seeker. He arrived here legally but then stayed after his visa expired.

And, I understand, Lammy wasn't certain on entering the chamber whether he was an asylum seeker or not.

So setting out what he knew might also have exposed what he didn't.

His team insist "it is incredibly important to know the facts" and they argue it was for the police in the first instance to do that publicly.

Really? It seems reasonable to ask both whether Lammy could or should have known more when he arrived in the chamber and whether he could or should have disclosed more when he was there.

The Conservatives later called for him to return to the Commons to set out what he knew. The former Tory leader Sir Iain Duncan Smith suggested he may have misled the Commons. The Liberal Democrats and Reform have been very critical too.

Some also suggest Lammy's manner – shouting "get a grip, man!" at Cartlidge, among other things – was a mistake.

Could he instead have chosen to set out what he did and didn't know about the case at the beginning of the exchanges, before he took any questions?

But it is the bigger picture here that really matters: the justice system is currently repeatedly failing in that most basic of its tasks – who should be in prison and who shouldn't.

The reasons for that are complex – with difficult questions for the courts, individual prisons, the Prison Service, the Ministry of Justice and the Home Office.

It is not a new problem, but it is a growing one, and one the government doesn't have a grip on. And that, if you are the justice secretary, is a problem.

President Donald Trump was swept to power for a second time on the back of a central campaign promise to tackle inflation.

The steep rise in the cost of living was top of voters' minds and Trump blamed President Joe Biden.

He also made sweeping promises to bring down prices for Americans "starting on day one".

One year on from his victory, BBC Verify revisits some of the president's claims.

Groceries

"When I win, I will immediately bring prices down, starting on Day One," Trump declared at an August 2024 news conference surrounded by packaged foods, milk, meats and eggs.

Official data - which includes a four-month period when Biden was still president - shows grocery prices rose by 2.7% in the 12 months to September 2025, with some items seeing significantly sharper increases:

• Coffee: 18.9%
• Ground beef (minced beef): 12.9%
• Bananas: 6.9%

Since Trump took office in January, the data also shows that apart from one recorded fall in April, grocery prices have risen each month.

"The president of the United States has very little control over the price of food, especially in the short term," food economics expert Professor David Ortega told BBC Verify.

Trump's tariffs are driving up prices of certain foods, he said - a third of coffee consumed in the US comes from Brazil and therefore has a 50% tariff.

Trump's illegal immigration crackdown may also have had an impact, Ortega adds, especially in farming where as many as 40% of workers are estimated to be undocumented, which is close to a million people.

"As you know, farmers and companies have to raise wages in order to attract more labour. But trying to quantify those impacts in terms of price increase is almost impossible at the moment."

Diane Swonk, the chief economist for KPMG, believes tariff and immigration policy changes have contributed to higher costs.

"There's no question that those shifts are now starting to show up as inflation pressures," she said.

But she adds that other factors, including weather events, have contributed.

"On coffee you had climate issues for a very bad growing season and that was exacerbated by a tariff on Brazil and also Colombia," she said.

A White House official told BBC Verify President Trump did not control weather patterns in South America and coffee prices hikes were a global phenomenon.

Data that tracks the cost of coffee shows prices have risen globally, peaking in February, but are now falling.

The same official said the president was addressing rising beef prices by temporarily increasing imports.

While grocery prices are up overall, not every item has become more expensive.

When Trump succeeded Biden in January, the price of a dozen large eggs was $4.93 (£3.79), rising to a record high of $6.23 (£4.78) in March following bird flu outbreaks.

Since then prices have fallen to $3.49 (£2.68) a dozen.

"President Trump's supply-side policies are taming Joe Biden's inflation crisis," White House Spokesman Kush Desai said.

Other items that have fallen in price over the past 12 months include: butter and margarine (-2%), ice cream (-0.7%) and frozen vegetables (-0.7%).

Electricity

During his campaign, Trump pledged to cut electricity bills sharply.

"Under my administration we will be slashing energy and electricity prices by half within 12 months, at a maximum 18 months," he told a rally in August 2024.

Since he became president, prices have risen.

The latest figures show average residential electricity rates reached 17.62 cents per kWh (kilowatt hour) in August 2025 - up from 15.94 cents per kWh in January 2025, according to the US Energy Information Administration.

"It was technically impossible [to halve prices] at the time he made the promise," according to Professor James Sweeney from the Stanford Precourt Institute for Energy.

Electricity prices not only reflect the cost of generation but also the expense of delivering it through "the wires and the transformers and everything else", he explained.

Prof Sweeney attributes the increase to both demand and supply issues.

"We have a surge in demand mostly driven by data centres. People creating images using artificial intelligence are using significant amounts of electricity."

He added that cuts to renewable energy subsidies and tariffs on imported steel - which raise the cost of building new power generators - have also pushed up prices.

Swonk agreed that the AI boom is pushing up prices, especially for those on lower incomes.

"It exacerbates inequality because consumers that have more access to solar panels and renewables tend to be wealthier households," she said.

In response a White House official said that Trump was expanding coal, natural gas and nuclear power, which was "the only viable way to meet the growing energy demand and to lower energy prices".

Cars

At a campaign rally in September 2024, Trump extended his grocery pledge to cars, telling supporters: "We're going to get the prices down… groceries, cars, everything".

However, the average price of a new car topped $50,000 (£38,411) for the first time ever in September, up from $48,283 (£37,092) in January according to Kelley Blue Book, a US vehicle valuation research company.

Car prices typically rise 2-3% a year, explained Erin Keating from Cox Automotive.

"Tariffs, which have been the biggest factor in the automotive industry over the last 12 months, have been nothing but inflationary."

She explained new car prices are increasing by about 4% a year, with tariffs contributing at least one percentage point.

"We really think in 2026 that's going to go higher because most of the manufacturers are holding their fire on raising prices directly due to tariffs, but they're going to have to come in at some point."

Keating did point to tax breaks for people in Trump's spending bill, which she believes may incentivise people to buy new cars.

When asked about the rising price of cars, a White House official told BBC Verify the administration had taken historic regulatory actions to "reverse the left's radical energy scam and save billions annually".

Gasoline

Trump made a specific campaign pledge of "getting gasoline below $2 a gallon".

On the day he entered the White House the average price for a gallon of "regular" gas was $3.125 (£2.33) according to the American Automobile Association (AAA).

While a long way short of his pledge to get prices below $2, the price of a gallon of gas has fallen to a national average of $3.079 (£2.36).

In response, a White House official pointed us to a gas price comparison website, which had a slightly lower national average of $2.97 (£2.38) per gallon compared with the AAA's data.

The official added that President Trump has quickly unleashed American energy to make gas affordable again for families across the country.

What do you want BBC Verify to investigate?

From an embankment overlooking Gaza City, there's no hiding what this war has done.

The Gaza of maps and memories is gone, replaced by a monochrome landscape of rubble stretching flat and still for 180 degrees, from Beit Hanoun on one side to Gaza City on the other.

Beyond the distant shapes of buildings still standing inside Gaza City, there's almost nothing left to orient you here, or identify the neighbourhoods that once held tens of thousands of people.

This was one of the first areas Israeli ground troops entered in the early weeks of the war. Since then they have been back multiple times, as Hamas regrouped around its strongholds in the area.

Israel does not allow news organisations to report independently from Gaza. Today it took a group of journalists, including the BBC, into the area of the Strip occupied by Israeli forces.

The brief visit was highly controlled and offered no access to Palestinians, or other areas of Gaza.

Military censorship laws in Israel mean that military personnel were shown our material before publication. The BBC maintained editorial control of this report at all times.

Asked about the level of destruction in the area we visited, Israeli military spokesman Nadav Shoshani said it was "not a goal".

"The goal is to combat terrorists. Almost every house had a tunnel shaft or was booby-trapped or had an RPG [rocket-propelled grenade] or sniper station," he said.

"If you're driving fast, within a minute you can be inside of a living room of an Israeli grandmother or child. That's what happened on October 7."

More than 1,100 people were killed in the Hamas attacks on Israel on 7 October 2023, and 251 others taken hostage.

Since then, more than 68,000 Gazans have been killed, according to the Hamas-run Health Ministry there.

The bodies of several hostages had been found in this area, Lt Col Shoshani said, including that of Itay Chen, returned to Israel by Hamas this week. Searches are continuing for the missing bodies of another seven hostages.

The Israeli military base we travelled to is a few hundred metres from the yellow line – the temporary boundary set out in US President Donald Trump's peace plan, which divides the areas of Gaza still controlled by Israeli forces from the areas controlled by Hamas.

Israel's army has been gradually marking out the yellow line with blocks on the ground, as a warning to both Hamas fighters and civilians.

There are no demarcations along this part of the line yet - a soldier points it out to me, taking bearings from a small patch of sand between the grey crumbs of demolished buildings.

The ceasefire is almost a month old, but Israeli forces say they are still fighting Hamas gunmen along the yellow line "almost every day". The piles of bronze-coloured bullet casings mark the firing points on the embankments facing Gaza City.

Hamas has accused Israel of violating the ceasefire "hundreds of times", and Gaza's Hamas-run Health Ministry says more than 240 people have been killed as a result.

Col Shoshani said that Israeli forces were committed to the US-led peace plan, but that they would also make sure that Hamas no longer posed a threat to Israeli civilians, and would stay as long as necessary.

"It's very clear to everyone that Hamas is armed and trying to control Gaza," he said. "This is something that will be worked out, but we're far from that."

The next stage of the US-led plan requires Hamas to disarm and hand over power to a Palestinian committee overseen by international figures including President Trump.

But rather than give up its power and weapons, Col Shoshani said, Hamas was doing the opposite.

"Hamas is trying to arm itself, trying to assert dominance, assert control over Gaza," he told me. "It's killing people in broad daylight, to terrorise civilians and make sure they understand who is boss in Gaza. We hope this agreement is enough pressure to make sure Hamas disarms."

Israeli forces showed us a map of the tunnels they said that soldiers had found beneath the rubble we saw – "a vast network of tunnels, almost like spider's web" they said – some already destroyed, some still intact, and some they were still searching for.

What happens in the next stage of this peace deal is unclear.

The agreement has left Gaza in a tense limbo. Washington knows how fragile the situation is - the ceasefire has faltered twice already.

The US is pushing hard to move on from this volatile stand-off to a more durable peace. It has sent a draft resolution to UN Security Council members, seen by the BBC, which outlines a two-year mandate for an international stabilisation force to take over Gaza's security and disarm Hamas.

But details of this next stage of the deal are thin: it's not clear which countries would send troops to secure Gaza ahead of Hamas disarmament, when Israel's troops will withdraw, or how the members of Gaza's new technocratic administration will be appointed.

President Trump has outlined his vision of Gaza as a futuristic Middle Eastern hub, built with foreign investment. It's a far cry from where Gaza is today.

Largely destroyed by Israel, and seen as an investment by Trump, the question is not just who can stop the fighting, but how much say Gazans will have in the future of their communities and lands.

Donald Trump's sweeping use of tariffs in the first nine months of his second term was sharply questioned during oral arguments before the Supreme Court on Wednesday.

Chief Justice John Roberts, and justices Amy Coney Barrett and Neil Gorsuch – three conservative jurists considered swing votes in this case - peppered US Solicitor General John Sauer, representing the president's administration, during his more than 45 minutes before the court.

They were joined by the court's three liberal justices, who also expressed scepticism about whether federal law – and the US Constitution – give the president authority to unilaterally set tariff levels on foreign imports.

"The justification is being used for power to impose tariffs on any product from any country in any amount, for any length of time," Roberts said.

If the court ruled for Trump in this case, Gorsuch wondered: "What would prohibit Congress from just abdicating all responsibility to regulate foreign commerce?"

He added that he was "struggling" to find a reason to buy Sauer's arguments.

The case centres around a 1977 law, the International Emergency Economic Powers Act (IEEPA), that Trump's lawyers have said gives the president the power to impose tariffs. Although the Constitution specifically vests Congress with tariff authority, Trump has claimed that the legislature delegated "emergency" authority to him to bypass longer, established processes.

Sauer asserted that the nation faced unique crises – ones that were "country-killing and not sustainable" - that necessitated emergency action by the president. He warned that if Trump's tariff powers were ruled illegal, it would expose the US to "ruthless trade retaliation" and lead to "ruinous economic and national security consequences.

Trump first invoked IEEPA in February to tax goods from China, Mexico and Canada, saying drug trafficking from those countries constituted an emergency.

He deployed it again in April, ordering levies from 10% to 50% on goods from almost every country in the world. This time, he said the US trade deficit - where the US imports more than it exports - posed an "extraordinary and unusual threat".

• What happens if the Supreme Court rules Trump's 'reciprocal' tariffs illegal?
• India-US sign 10-year defence pact amid tariff turmoil
• Trump hails 'amazing' meeting with China's Xi but no formal trade deal agreed

Those tariffs took hold in fits and starts this summer while the US pushed countries to strike "deals".

Lawyers for the challenging states and private groups have contended that while the IEEPA gave the president power to regulate trade, it made no mention of the word "tariffs"

Neil Katyal, making the case for the private businesses, said it was "implausible" that Congress "handed the president the power to overhaul the entire tariff system and the American economy in the process, allowing him to set and reset tariffs on any and every product from any and every country, at any and all times."

He also challenged whether the issues cited by the White House, especially the trade deficit, represent the kind of emergencies the law envisioned.

Suppose America faced the threat of war from a "very powerful enemy", Samuel Alito - another conservative justice – asked. "Could a president under this provision impose a tariff to stave off war?"

Katyal said that a president could impose an embargo or a quota, but a revenue-raising tariff was a step too far.

For Sauer, this was a false choice. Presidents, he said, have broad powers over national security and foreign policy – powers that the challengers want to infringe on.

A key question could be whether the court determines whether Trump's tariffs are a tax.

Several justices pointed out that the power to tax – to raise revenue – is explicitly given to Congress in the Constitution.

Sauer's reply was that Trump's tariffs are a means of regulating trade and that any revenue generated is "only incidental".

Of course, Trump himself has boasted about the billions his tariffs have generated so far and how essential this new stream of funding is to the federal government.

Treasury secretary Scott Bessent, who attended the hearing, made no comment when asked by the BBC what he thought of the hearing. Secretary of Commerce Howard Lutnick, also in court, flashed a thumbs-up.

US Trade Envoy Jamieson Greer was in court, along with Minnesota Senator Amy Klobuchar, who said outside after arguments, that she was "hopeful" based on the questions asked that the court would overturn the tariffs.

"I thought they were very good questions," she said, describing tariffs as an "unconstitutional power grab" by the president.

If a majority of the Supreme Court rules in Trump's favour, it will overturn the findings of three lower courts that already ruled against the administration.

The decision, no matter how it works out, has implications for an estimated $90bn worth of import taxes already paid - roughly half the tariff revenue the US collected this year through September, according to Wells Fargo analysts.

Trump officials have warned that sum could swell to $1tn if the court takes until June to rule.

During oral arguments, Barrett grappled with the question of reimbursing such revenue, wondering if it would be a "complete mess".

Katyal responded by saying that small businesses might get refunds, but bigger companies would have to follow "administrative procedures". He admitted that it was a "very complicated thing".

In remarks on Wednesday, press secretary Karoline Leavett hinted that the administration already is looking at other ways to impose tariffs if the Supreme Court rules against them.

"The White House is always preparing for Plan B," she said. "It would be imprudent of the president's advisors not to prepare for such a situation."

Transportation Secretary Sean Duffy warned there will be a 10% reduction in air travel capacity at 40 major airports in the US starting Friday morning, if the government shutdown continues.

The decision was made because air traffic controllers have been reporting issues with fatigue, the head of the Federal Aviation Administration (FAA) said at a briefing with Duffy on Wednesday.

"It is unusual, just as the shutdown is unusual, just as the fact that our controllers haven't been paid for a month is unusual," said FAA chief Bryan Bedford

During the shutdown, now the longest in US history, controllers have had to keep working without pay, prompting some to call out sick or take side jobs.

The flight reductions will be gradual, starting at 4% of domestic flights on Friday, then rising to 5% on Saturday and 6% on Sunday, before hitting the full 10% next week, Reuters reported after the announcement, citing four unnamed sources.

The names of the affected airports - all high-traffic locations - will be released on Thursday, the officials said.

The cancellations could affect between 3,500 and 4,000 flights per day.

"We are seeing pressures build in a way that we don't feel - if we allow it to go unchecked - will allow us to continue to tell the public that we operate the safest airline system in the world," Bedford said.

Duffy said air travel is still safe, and the decision to cancel the flights was being made to maintain safety and efficiency.

If the shutdown continues and adds more pressure to the system, additional restrictive measures may be required, Bedford said.

A spokesperson for Southwest Airlines, the fourth-largest carrier in North America, said in a statement that the company is still evaluating how the flight restrictions will affect its services, and will let customers know as soon as possible.

"We continue to urge Congress to immediately resolve its impasse and restore the National Airspace System to its full capacity," the spokesperson added.

Delta Airlines declined to comment. The BBC has also reached out to other major US airlines.

Once government funds ran out on 1 October, most federal workers were sent home and told they would be paid once the government reopened. Those deemed essential, like controllers, though, had to keep doing their jobs without pay.

Almost immediately after the shutdown started, airports began feeling the effects. Some had to ground flights for hours after air traffic controllers called out sick, while others relied on controllers from other airports.

Nick Daniels, the president of the labor union representing more than 20,000 aviation workers, put the situation into stark terms on Wednesday.

"Air traffic controllers are texting 'I don't even have enough money to put gas in my car to come to work,'" he told CNN.

"We base what we do day in and day out on predictability," he said. "Right now there is no predictability."

Duffy warned earlier this week that the flight cancellations may be coming, as half of the country's 30 major airports experience staff shortages.

He previously said there's a risk that comes with air traffic controllers taking on additional jobs during the shutdown, and had threatened to fire controllers who do not come to work.

"They have to make a decision, do I go to work and not get a paycheque and not put food on the table? Or do I drive for Uber or DoorDash or wait tables?" Duffy said on ABC on Sunday.

Hamas has handed over to the Red Cross a coffin containing what it says is the body of another deceased hostage, the Israeli military has said.

The remains have been transferred to Israeli forces, who will take them to the National Centre of Foreign Medicine in Tel Aviv for identification.

Under the first phase of the US-brokered ceasefire deal with Israel, which started nearly a month ago, Hamas agreed to return all 20 living and 28 dead Israeli and foreign hostages it was holding within 72 hours.

Israel has accused Hamas of deliberately delaying the recovery of the dead hostages' bodies, while Hamas has insisted it is struggling to find them under rubble.

If the latest remains are confirmed as those of a dead hostage, it will mean six others are still in Gaza – including Israelis and foreign nationals.

All the remaining living Israeli hostages were released on 13 October in exchange for 250 Palestinian prisoners and 1,718 detainees from Gaza.

Israel has also handed over the bodies of 300 Palestinians in exchange for the bodies of the Israeli hostages and those of two foreign hostages - one of them Thai and the other Nepalese.

On Tuesday, the remains of Israeli-American soldier Itay Chen, 19, were returned.

Staff Sgt Chen was serving as a soldier in the IDF's 7th Brigade when Hamas-led gunmen attacked southern Israel on 7 October 2023.

The IDF said he was killed inside a tank during a battle in Kibbutz Nir Oz and that his body was taken to Gaza as a hostage by Hamas.

The slow progress over the return of the hostages has meant there has been no advance on the second phase of President Trump's Gaza peace plan. This includes plans for the governance of Gaza, the withdrawal of Israeli troops, the disarmament of Hamas, and reconstruction.

Israel has allowed members of the Palestinian armed group and Red Cross staff to search for remains in areas still controlled by Israeli forces.

All but one of the dead hostages still in Gaza were among the 251 people abducted during the Hamas-led attack on southern Israel on 7 October 2023, during which about 1,200 other people were killed.

Israel responded by launching a military campaign in Gaza, during which more than 68,800 people have been killed, according to the territory's Hamas-run health ministry.

Controversial Malaysian rapper Namewee has been remanded in custody in connection with the death of a Taiwanese influencer found dead in a Kuala Lumpur hotel bathtub two weeks ago.

Police say Namewee, 42, was the last person seen with 31-year-old Iris Hsieh, according to reports. She was in Malaysia to discuss a commercial video Namewee had agreed to direct, her social media manager told the BBC.

Namewee, who denies charges of illegal drug use and possession for which he was granted bail, is now back in custody to "assist in the investigation", police said after reclassifying her death as murder.

He turned himself in early on Wednesday, his lawyer said, and has been put on remand for six days.

'I won't run away'

The case has gone through many twists in the last few days.

According to Malaysian media reports, Namewee contacted emergency services at 12:30 local time (05:30 GMT) on 22 October, after he found Hsieh unresponsive in the bathroom.

Police arrested Namewee that same day, after they found nine blue pills believed to be ecstasy in the hotel room.

Despite denying he had used drugs, Namewee tested positive for several illicit substances, including amphetamines, methamphetamine, ketamine, and THC, police said.

On Monday, he pleaded not guilty to the drug charges and was released on bail.

Namewee has maintained his innocence over the past few days and accused local media of "chasing shadows" with their reports on the case.

The singer, known for his satirical and profanity-laced music, has 3.6m subscribers on YouTube and 856,000 followers on Instagram. Singing in Mandarin, he is hugely popular in Taiwan and China.

Hsieh was previously featured in Namewee's music video for China Reggaeton, a song he released in January 2020.

On Tuesday, Kuala Lumpur police chief Fadil Marsus told reporters Namewee had "gone into hiding" after Hsieh's case was reclassified from "sudden death" to murder.

At the same time, Mr Fadil said police were waiting for post-mortem and toxicology results to determine the cause of death.

In the early hours of Wednesday, Namewee posted a clip on Instagram saying he had arrived at the police station and would "fully co-operate with the police to provide answers to the public and the bereaved family".

"I won't run away," he added.

Who is Namewee?

Namewee, whose real name is Wee Meng Chee, has long courted controversy with his music.

Often seen wearing a beanie and sunglasses, he first gained popularity - and notoriety - in 2007 with his controversial remake of Malaysia's national anthem, Negaraku, which mocked the government.

The music video quickly went viral on YouTube and authorities considered charging him with sedition, but did not proceed after he made a public apology and removed the clip.

In 2016, he was arrested for his music video Oh My God, which features him rapping in front of places of worship around Malaysia. Authorities said the song insulted Islam and jailed him for four days.

His 2021 song Fragile poked fun at "little pinks" - young nationalists who rush to the defence of the Chinese government on the internet - and took digs at several sensitive issues, from Xinjiang to Taiwan sovereignty.

That track went viral among Mandarin-speaking audiences, but was banned by China. Speaking to the BBC in 2021, Namewee said he saw the ban as "part of my creative work".

"Some people think that my work is controversial, or that I have always been crossing the red line," he said at the time. "Sometimes I intend to do so... If I think more people should know about certain issues, I want more people to care."

Namewee has collaborated with other popular Mandarin artists, including Taiwanese rock duo Power Station and Chinese-Australian singer Kimberly Chen, and has been nominated three times for the best Mandarin male singer in Taiwan's Golden Melody Awards.

He has also ventured into filmmaking, both starring in and directing films, some of which have stirred controversy over their portrayals of race and religion.

Who is Iris Hsieh?

Compared to Namewee, Hsieh was not as famous across Asia, although she had a fairly strong following on social media and was known for posting photos of herself in revealing outfits.

Nicknamed the "nurse goddess" by her fans, she graduated from the Central Taiwan University of Science and Technology with a degree in nursing, according to China Press, a Mandarin newspaper published in Malaysia.

Hsieh rose to internet fame around 2019, Malaysian media reported, and released a personal photo album titled Angel Heart the next year.

She has about 545,000 followers on Instagram - her fifth account on the social media platform, after the last four were suspended for "adult sexual solicitation", CNA reported.

She was also active on OnlyFans, where she started an account in 2022.

Hsieh's social media manager, who asked only to be referred to as Chris, told the BBC that her family were unable to go to Malaysia to follow up on the case because of their "severe disabilities".

They have instead hired legal representatives there to act on their behalf, he said.

Mexico President Claudia Sheinbaum has said she will press charges against a man who groped her during a public appearance.

Mobile phone footage of the incident on Tuesday shows Sheinbaum speaking to a group of supporters on a street near the National Palace in Mexico City.

In the video, a man approaches her from behind and attempts to kiss her on the neck and place his hands on her body.

Sheinbaum moved away quickly and a member of her team stepped in, but she was visibly shaken. The offender has been arrested.

"My view is, if I don't file a complaint, what will happen to other Mexican women? If they do this to the president, what will happen to all women in our country?" Sheinbaum said at a news conference on Wednesday.

"I decided to press charges because this is something that I experienced as a woman, but that we as women experience in our country," she said. "I have experienced it before, when I wasn't president, when I was a student."

She added that she had decided to press ahead with bringing charges against the suspect as he had allegedly harassed other women in the crowd.

"A line must be drawn," she said.

Women's rights groups and feminist commentators have said the incident shows the extent of ingrained machismo in Mexican society, where a man believes he has the right to accost even the president if she is a woman.

Femicide is also a huge problem in Mexico, with a staggering 98% of gender-based murders estimated to go unpunished.

Sheinbaum promised to tackle the issue as a candidate, but so far in her administration there has been no discernible improvement in that area of violent crime.

The incident also comes amid discussions about presidential security and the wider safety of politicians.

As president, Sheinbaum has broadly followed the approach of her predecessor, Andres Manuel Lopez Obrador, in having close and regular contact with her supporters on the streets or in campaign events.

On occasion, that has presented security concerns for her team. However, she confirmed in her new conference she had no intention of changing her policy of interacting with her supporters.

The incident also happened just days after the murder of Carlos Manzo, the mayor of Uruapan, a municipality in the violent state of Michoacan, at the local Day of the Dead celebrations.

Manzo had called on Sheinbaum for greater federal support in Uruapan in the fight against drug cartels. Around 35 candidates were killed in the lead up to the general election last year in what was considered the bloodiest campaign in modern Mexico.

Since taking office, Sheinbaum has made in-roads in improving the country's dire security situation, particularly clamping down on fentanyl-trafficking – a key issue for her US counterpart, President Trump.

French police have launched an investigation into sex-trafficking linked to the disgraced businessman Mohamed Al Fayed, who died two years ago.

The police investigation, ordered by the Paris prosecutor's office, will focus on "potential acts of aggravated human trafficking… with multiple victims," according to correspondence seen by the BBC. Prostitution and one case of rape are also being investigated.

Al Fayed's Ritz Hotel in Paris will likely be a target of the investigation, amid claims from victims that staff knew about or facilitated the abuse of women.

In a statement, the Ritz said it was "deeply alarmed" by the allegations of abuse and it would cooperate "fully" with authorities.

The trafficking investigation marks a new twist in a series of legal battles linked to Al Fayed's violent crimes and to the search – both before and since his death – for some sort of justice for his many victims.

An American woman, Pelham Spong, 40, played a key role in triggering this investigation in France, where it is alleged that Al Fayed moved young female staff from the Ritz to his private house in Paris and to various yachts and family homes on the Mediterranean coast.

Ms Spong was living in Paris in 2008 when she applied for a job working as a personal assistant for the Al Fayed family in Monaco.

She was brought to London several times, subjected to an intrusive gynaecological examination, and then – she alleges - sexually assaulted by Al Fayed in his office on Park Lane.

"He told me the job entailed sleeping with him," Ms Spong said, adding that she declined the offer on the spot.

"I didn't realise I was a victim of sex trafficking until this past year when I… saw the scale and scope of the abuse and realised that it was a pattern and a system and a machine," she told the BBC in an interview in Paris.

A few months ago, Ms Spong, now living back in the USA, came to Paris to report her experiences to the French police, hoping that it might persuade other women to come forward with evidence of their own abuse.

"It's a big step that the prosecutors decided to open an investigation. [Ms Spong] has a really good case because she kept a lot of materials. It will be very strong," her lawyer, Anne-Claire Le Jeune told the BBC.

Ms Spong said it is "so much easier to dismiss the actions of an evil man that's dead".

"And you can't learn anything from that as a society. So how do you prevent this happening again?

"Well, first, you have to name what it... It's critical to call it what it is, trafficking, so that we can prevent it," she said.

Al Fayed is also being investigated in the UK, where more than 140 people have reported him to the Met Police.

The extent of Al Fayed's predatory behaviour was first brought to light by a BBC documentary and podcast, broadcast in September 2024.

Al Fayed: Predator at Harrods heard testimony from more than 20 female ex-Harrods employees who said Al Fayed sexually assaulted or raped them. Since then, dozens more women have come forward with similar experiences.

After the broadcast, the Met revealed it had been approached by 21 women before Al Fayed's death, who accused him of sexual offences including rape, sexual assault and trafficking. Despite this, he was never charged with any offences.

Ms Spong herself says she spoke to British police about Al Fayed in 2017 but was told he was too ill to be questioned.

Earlier this year, the Met wrote to alleged victims apologising, saying it was "truly sorry" for the distress they have suffered because Al Fayed will never face justice.

The force is currently investigating its handling of historical allegations against Al Fayed and looking into whether others could face charges for enabling his behaviour.

Harrods has set aside more than £60m in its plan to compensate alleged victims of Al Fayed's abuse.

In a statement announcing the scheme, Harrods said: "While we cannot undo the past, we have been determined to do the right thing as an organisation, driven by the values we hold today, while ensuring that such behaviour can never be repeated in the future."
