City plans to triple system of underground pipes that distribute chilled river water, reducing need for individual cooling units

As heatwaves intensify across Europe, most cities are reaching for a familiar fix of more air conditioning. But in 1990s Paris, planning began for a different kind of solution: one of the world’s largest district cooling networks.

The system has 120kms (75-miles) of underground pipes distributing chilled water to museums, offices, hospitals, schools and other public buildings including the Louvre, the Grand Palais, and some luxury hotels and office districts. Instead of thousands of individual air-conditioning units, cooling is produced centrally and shared across the city like a utility.

They were a big 00s buzz band – but looked in danger of fading out. Empowered by fatherhood and anger at war and AI, the New Yorkers explain why they ‘really showed up’ again

Suits. Gnomic poetry. Moody, insistent riffs. It used to be that you’d know what to expect from NYC rockers Interpol. The band’s first two albums, in the early 00s, were blockbuster successes, shifting half a million units each thanks to dramatic songs also fit for jerking around at an indie disco. Interpol duly jumped up to a major label, but then quickly fell back down again. Their talismanic bassist Carlos Dengler quit, and the band settled into a decade of solidly successful but pretty predictable albums. The most recent, 2022’s The Other Side of Make Believe, only reached No 178 on the US charts.

So it’s a bit unexpected that their upcoming eighth album, This Mirror Weighs a Ton, is their masterpiece. “We just all really showed up,” frontman-guitarist Paul Banks says of a band that has swelled to a quintet as two touring musicians, bassist Brad Truax and keyboardist Brandon Curtis, become full-time members. “The lyrics on the last record, it’s really hard for me to identify with what I was doing,” Banks continues. “I felt as if I made some mistakes.” What were they? “I don’t want to draw attention to them! I just didn’t want to walk away with that feeling again.”

The Makerfield MP’s surge towards No 10 is a seductive ad for the power of positive politics. How long that proves effective depends on his next moves

The creation of hope is a vital but risky part of democratic politics. Leaders or would-be leaders who arouse hope attract supporters, motivate activists, achieve momentum and win over voters – and then have a chance of holding together political parties, governments and societies in harder times. From Barack Obama to Clement Attlee, Salvador Allende to Zohran Mamdani, leaders from across the left in particular have heavily relied on hope to launch and sustain their ruling projects.

Meanwhile, an absence of hope has quickly doomed other left of centre governments. Keir Starmer’s decision, only eight weeks into his premiership, to summon the media to the Downing Street garden and tell them that “things will get worse before we get better” in the UK was a mistake from which his administration never recovered. In a society where most lives have been getting harder since the 2008 financial crisis, Starmer’s downbeat manner, however justified by the deep problems he inherited from the Tories, was not an emotional register that much of the electorate desired.

Sarah Steele waives anonymity to call for greater scrutiny of how US military courts are allowed to ‘rip apart’ vulnerable witnesses in the UK

• Why did a US fighter pilot avoid British trial after strangling a woman in England?

• Explainer: how the US bypasses British courts

A woman strangled by an American fighter pilot at his home in an English city has come forward to criticise the handling of his prosecution via a US court martial, a process she described as “military first, justice second”.

Sarah Steele, a British academic, has come forward to speak about the “distressing and degrading” experience she had with the US military justice system after she was assaulted by the airman in Cambridge.

It was not a match of high distinction, but all the Socceroos needed was a pass against Paraguay, and their 0-0 in San Francisco Bay Area stadium booked a place in the World Cup knock-out rounds for the third time in their history.

A much-changed Australia side controlled large parts of the match, but with both teams knowing that a draw would be enough to qualify for the last 32, there were long stretches without impetus.

Packed with fun memories from Ben Elton and Stephen Fry plus heartbreaking regret from his former partner, the Bottom star is so adored that this documentary risks descending into cringe – but his punky spirit shines through

Rik Mayall: Magnificent B’Stard is a homage to the man and an elegy for what you have to presume were the lost youths of most of the viewing audience. I don’t know what the current youth would make of it. I suppose they’re not watching television anyway, so the question’s moot.

Plus, of course, it doesn’t matter. This is 90 minutes of television for us – the generation that grew up with Mayall on screen as Rick the Poet (“This is my angriest poem – Theatre!”), then self-styled investigative reporter from and mostly in Redditch, Kevin Turvey, then in The Young Ones as anarchist sociology student Rick and on through its less wildly popular follow-up Filthy Rich & Catflap. Then there was his unforgettable turn as Lord Flashheart in Blackadder II (and as the horndog lord’s equally priapic descendant Squadron Commander Flashheart in Blackadder Goes Forth); the unexpected pivot towards a more restrained demonstration of his comic talents as oleaginous, ruthless, corrupt, entirely fictional Tory MP Alan B’Stard in Marks and Gran’s brilliant The New Statesman; a Hollywood punt as Drop Dead Fred; then the huge success of Bottom as a sitcom and a live show throughout the 90s until a terrible quad biking accident in 1998 trimmed his sails.

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

The heatwave scorching western Europe is the most severe and widespread ever and is only possible due to the climate crisis driven by fossil fuel burning, scientists have said.

Almost half of Europe’s 850 largest cities are also enduring their worst ever heat stress, a combination of temperature and humidity, they found. Muggier conditions mean sweating is less effective at cooling the body, making heatwaves even more dangerous.

Charles and Camilla to remain at Clarence House and are said to want the public to have more access to ‘monarchy HQ’

• King Charles’s tax bill: what did we learn and what is still in the dark?

• Crown estate makes more than £1bn profit for third year running

King Charles and Queen Camilla will not move into Buckingham Palace when £369m of buildings works to update it finish next year, preferring to remain at Clarence House, their London home nearby.

The announcement came as it was revealed the king paid £12.9m in income and capital gains tax in 2024-25 on his personal income, known as the privy purse, making him among the country’s top 100 taxpayers. Prince William paid £7.76m for the same period.

Kremlin may attempt to test Nato cohesion as Russia comes under growing pressure from Ukraine, according to sources from two countries

Two countries on Nato’s eastern flank have warned that Russia is preparing a possible “provocation” in the Baltic states or Poland in an effort to test the cohesion of the western military alliance.

Western sources also fear there could be danger on the horizon because the Kremlin is coming under pressure from Ukraine’s campaign of long-range attacks on targets near Moscow and St Petersburg.

Planning permission has been sought for three additional military sites

Home Office plans to use three more former military sites to house thousands of asylum seekers have been condemned as “arrogant”, “costly” and “a political fix” by refugee charities and local stakeholders.

Planning permission is being sought to build “basic” accommodation at MOD Bicester in Oxfordshire, RAF Barnham in Suffolk and RAF Linton-on-Ouse in North Yorkshire, a statement said. These new sites could house 3,750 claimants, the government has claimed.
