Amid a cost of living crisis, pricey patisserie is all the rage – and not just in London. Our reporter goes on a crawl to find out if a tart can really be worth £45

There was a time when you could get a stuffed vanilla cream slice or a neon-pink Tottenham cake for about £1 on the leafy, residential corner of Hackney, east London, where I stand today. But the branch of Percy Ingle bakery that was here for nearly 50 years is gone. In its place sits Fika, a cafe where a cinnamon bun costs £4.20 and a pistachio croissant will set you back nearly £5.

In comparison with other bakeries, however, Fika’s pastries are a bargain. At Copains, a Parisian favourite that opened its first UK branch in central London late last year, a large babka (about the same size as a supermarket chocolate twist) will set you back £12.50, while an eclair costs £11.90. In Harrods’ food hall, a stuffed, savoury croissant topped with gold leaf is £12. At Cedric Grolet, located inside the luxury Berkeley hotel, a hazelnut cookie will leave you £25 out of pocket. Yes, the age of the £10-plus pastry has arrived.

Her first album was a huge hit – then she faced the sudden tragedy of her husband’s early death. She describes the rupture of grief, her return to music and the harsh reality of fame as a woman in the 00s

Twenty years ago, Corinne Bailey Rae had her first huge hit single, and her only one. Put Your Records On was one of the great feelgood anthems of 2006. A warm, breezy hymn to authenticity, its key message was keep playing those songs you love, and don’t give a toss about what others tell you is cool. The single was accompanied by her first self-titled album, which topped the charts in the UK and reached number four in the US.

If there was one thing Bailey Rae seemed assured of, it was longevity. She wrote or co-wrote her own songs, had a voice that was compared to that of Billie Holiday and Minnie Riperton, there was a timelessness to her music and she was super smart (four As at A-level, if you must know). Then she was hit by a tragedy that derailed her. In 2008, her husband of seven years and fellow musician Jason Rae died of an accidental drug overdose.

The PM’s in-tray is overflowing. But he can’t afford to neglect the real issue that is distorting our politics and the way we live

At home and abroad, Labour and its leader are under siege. Though the Gorton and Denton result is history now, the repercussions roil his party and underpin the fight for its future.

Abroad, the policy rift within the Labour tribe is just as bad, with the fear that the party will be dragged backwards into the wreckage of another illegal war in the Middle East. Yet again Labour and Starmer are damned both ways, with much of the party raging at its leader and a “very disappointed” Donald Trump angry, not appeased.

The music on Styles’s new album is muted, subtle and pleasant – but from the title downwards, he has a real problem with words

Everything about the launch of Harry Styles’s fourth solo album underlines that its author is a very big deal indeed. Record stores in the UK are opening at midnight or first thing in the morning on the day of release, the better for fans to avail themselves of a copy at once. Styles has been announced as curator of this year’s Meltdown festival at London’s Southbank Centre, an honour previously bestowed on Scott Walker, Patti Smith, Yoko Ono, Ornette Coleman and David Bowie. Last week’s Brit awards featured not merely a beautifully choreographed performance of the album’s lead single, Aperture, but a comedy skit that was, essentially, a two-and-a-half-minute-long advert for Styles’s new album: there was no doubt who the organisers thought the star of the show was. Most striking of all, the accompanying tour largely eschews actual touring in favour of lengthy residencies in one venue per country, or even continent: North America is covered by a staggering 30 dates at New York’s Madison Square Garden. The expectation seemed to be that Styles’s fans are so devoted, they’ll cross the country to see him, rather than vice versa.

This sense, that people will travel wherever Harry Styles wants them to, attends the album itself. It is devoid of unequivocal pop bangers along the lines of As It Was or Watermelon Sugar. Aperture’s hazy, post-club mood wasn’t a soft launch. Whether it’s dealing in mid-tempo house beats topped with plangent piano chords, as on American Girls, or the acoustic singer-songwriter-isms of Paint By Numbers, a lot of what’s here feels like music made in the small hours, with the curtains drawn against the dawn. It somehow manages to sound understated even on Are You Listening Yet? – which variously features a clattering dance rhythm, a bassline not unlike that of Reel 2 Real’s I Like to Move It and a spoken word vocal that inexorably recalls Robbie Williams’s Rock DJ – perhaps because it doesn’t really have a chorus, or rather, the part you assume is going to lead into the chorus turns out to be the chorus itself.

As a historian, I’ve studied the major consumer boycotts of history. We can take down ChatGPT and send a powerful signal to Silicon Valley

OpenAI, the company behind ChatGPT, is on track to lose $14bn this year. Its market share is collapsing, and its own CEO, Sam Altman, has admitted it “screwed up” an element of the product. All it takes to accelerate that decline is 10 seconds of your time.

A grassroots boycott called QuitGPT has been spreading across the US and beyond, asking people to cancel their ChatGPT subscriptions. More than a million people have answered the call. Mark Ruffalo and Katy Perry have thrown their weight behind it. It is one of the most significant consumer boycotts in recent memory, and I believe it’s time for Europeans to join.

Getting platforms to comply with the restrictions was no small feat. But it’s too early to measure the real-world mental health outcomes

As the UK becomes the latest country to consider following Australia’s lead on a social media ban for teenagers, a question Australians are repeatedly being asked is: how is it going?

“Our data is still minimal,” says Caroline Thain, national clinical adviser with the mental health organisation Headspace. “We’re really waiting for a few more months before we do a deeper dive.”

Tehran yet to choose replacement for late Ali Khamenei as US-Israeli war on Iran enters fifth day

• Analysis: Trump administration still not settled on reasons for war

• Tell us: how have you been affected by the conflict?

Lebanese state media said that four people were killed and six more were wounded in an Israeli strike on a building in Baalbek in eastern Lebanon on Wednesday.

“The initial toll is four killed and six wounded, and work is underway to rescue families from under the rubble,” Lebanon’s state-run National News Agency said.

Religious freedom group says 200 troops sent complaints of superiors using extremist Christian rhetoric to justify war

• Middle East crisis – live updates

US military commanders have been invoking extremist Christian rhetoric about biblical “end times” to justify involvement in the Iran war to troops, according to complaints made to a watchdog group.

The Military Religious Freedom Foundation (MRFF) says it has received more than 200 complaints from service members across all branches of the armed forces, including the marines, air force and space force.

South Korea’s Kospi leads market sell-off across Asia and Middle East, despite Trump’s suggestion US Navy could protect vessels moving through vital waterway

Global markets tumbled further on Wednesday despite Donald Trump’s offer to have the US navy escort tankers through the strait of Hormuz and the US military’s claim that there is “not a single Iranian ship underway” in the crucial waterway.

The Middle East conflict has crippled the strait, which was in effect closed by Iran after strikes by the US and Israel this weekend, raising fears of a sustained energy supply crisis that reverberated around the world.

Evacuations near RAF base have reignited debate as Cypriots question the risks of hosting western military sites

All his life, like his parents before him, Giorgos Konstantinos has learned to live next to RAF Akrotiri on Cyprus.

He has dealt with the roar of planes, the comings and going of military vehicles and the war games. But never has Konstantinos, the village’s vice-mayor, witnessed anything quite like the events of the past two days.
