He lit up the 1970s with a string of hits, before falling out of the public eye. But was any man ever more connected? He discusses extraordinary encounters with Muhammad Ali and Keith Moon – and why he stormed out of Big Brother

Leo Sayer has stories. Boy, does he have stories! Muhammad Ali? Stories. Keith Moon? Stories. Elvis Presley? Stories. I’ve never met anybody with so many stories. He’s in Australia, where he lives, when we speak by video link. The pint-sized pop star with the mop of curly hair is 77 and still bouncing like a Superball.

Back in the 70s, he was famous for his turbo-charged energy. On his first Top of the Pops appearance with his breakthrough hit, The Show Must Go On, he dressed as a pierrot. If you’re looking for the footage, you won’t find it. Paedophile presenter Jimmy Savile played such a prominent role that the video was disappeared. “He was creepy. He wouldn’t get off the fucking stage, so they can never show my first performance. I’m sure he fancied me.”

She has lots of different ways to remind me to breathe. These still my thoughts, and remind me that I’m loved in a way that weighs as much as whatever heartbreak, stress or exhaustion I’m experiencing

My favourite photograph of my mother, Linda, and I was taken at my wedding. I’m not sure we realised we were being photographed. Two artist friends were walking around with film cameras, shooting the kind of things they knew that Hiraki, my husband, and I would like. My mother and I are standing shoulder to shoulder, under a young tree. I love how the shapes of our necklines are like a sartorial call and response, how our smiles are so peaceful, how we are both looking outwards.

It’s not that this picture captures a specific moment. Rather, it taps into a certain quality of my mother’s love that is timeless, unbound by circumstance or context. She has always loved my sister and I exactly like this: gently, spaciously and alongside.

Once violently defended from extinction, Welsh is still a part of daily life. By learning my family’s language, I hoped to join their conversation

My maternal grandmother died 20 years ago. The funeral was held in a small Methodist chapel in the lush Conwy valley of north Wales. Her entire life – she had almost reached 100 – was spent in these hills. The drizzle that morning had slicked the trees and turned the slate of the chapel black. Our family, gathered under umbrellas, entered in order of seniority: Mum, now the family elder, with Dad on her arm, then my six aunts and uncles with their spouses, and finally the cousins, led by my brother Mark and me.

The room was austere. White walls, sturdy wooden furniture, a plain cross on the wall. Our family squeezed into box pews in the centre of the chapel. A couple of older men among the crowd reminded me of my grandfather, who had died decades earlier: similar thatches of black hair; dark, weathered complexions; history-book faces.

There was time for Kemi to embarrass herself again as she explained how we were both at war and not at war

Taxi for Kemi. It’s only a matter of time before Tory MPs start thinking the unthinkable and hand their leader her P45. It could be happening even now. This week’s prime minister’s questions can only have concentrated a few minds. Buyer’s remorse has long since passed. Some have now moved through the five stages of grief.

First there was the denial. Despite evidence to the contrary, Kemi was doing better than expected. It didn’t matter that she had taken the Tories from the high 20s to the mid-teens in the opinion polls. She was destined for stardom. It was just a matter of the country keeping up with her brilliance.

What have we learned from release of files relating to former peer’s appointment – and sacking – as UK ambassador to Washington?

We now have the first tranche of documents promised by the government connected to the appointment of Peter Mandelson as the UK’s ambassador to Washington – 147 pages from a mass of information believed to total in the hundreds of thousands.

Mandelson has previously denied any wrongdoing, and his lawyers have said he does not intend to make any further statement at this time. Here is what we have learned from the files – and what we do not yet know.

Experts share tips on dressing as the most authentic version of yourself and avoiding the draw of the latest microtrends

How would you define your personal style? Is it cottagecore? Tomato girl? Whimsigoth? Quiet luxury? Maybe you don’t know what these terms mean (congratulations) and maybe you do (my condolences).

Like unwelcome nose hairs, new microtrends seem to sprout from the depths of social media every other week. In some ways, their pervasiveness has made style seem more accessible than ever. They reduce aesthetics to mathematical equations that you can solve by buying up a bunch of fast fashion. By the time these cheap, mass-produced items dissolve into microplastics – which they will, quickly – other aesthetic trends will have replaced them.

Iranian officials warn of ‘war of attrition’ and global economic chaos as energy supplies are throttled

• Middle East crisis – live updates

Iran dramatically escalated its strategy of striking civilian infrastructure and transport networks across the Gulf on Wednesday, attacking commercial ships and targeting Dubai’s international airport as US and Israeli warplanes launched new waves of strikes on the Islamic Republic.

Senior Iranian officials struck a defiant tone, warning of a long “war of attrition” that would threaten global economic chaos as energy supplies from the region were throttled.

Vast release of emergency crude reserves fails to quell mounting fears around energy supply crunch, rattling global markets

Oil prices again topped $100 per barrel on Thursday as widespread Iranian attacks on Middle Eastern energy facilities overshadowed a vast release of government reserves.

As Donald Trump vowed to “finish the job” and press ahead with the US-Israel war on Iran, the country’s regime stepped up retaliatory strikes on economic targets across the region.

From fuel caps to four-day work weeks, the Middle East conflict has left the world’s top crude oil importing region desperate to shore up supplies

Donald Trump has scrambled in recent days to reassure the world that the economic impact of his war on Iran can be contained.

Sure, one of the most important waterways in global trade has, in effect, been shut for almost two weeks – but it might reopen before long. In the meantime, US oil-related sanctions on “some countries” will be lifted. And besides, the entire conflict could be over soon.
