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 are rules and world leaders must insist they are honoured in practice and in spirit. After this atrocity in Iran, a more effective tribunal for crimes against children is essential

The killing of a reported 168 people, primarily schoolgirls, in the bombing of the Shajareh Tayyebeh school in Minab in Iran has shaken to its very core the conscience of the world.

The attack, carried out nearly two weeks ago when classes were under way, reduced the school building to rubble. Parents who had sent their daughters to school discovered minutes later that classrooms had become mass graves.

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.

Tens of thousands of residents and tourists have left UAE since the US and Israel started bombing Iran two weeks ago, leaving beach bars, malls and hotels eerily empty

In the playground of the rich, nobody wanted this war. For decades, Dubai built itself up as a sanctuary of unadulterated consumerism visited by tourists the world over.

But now, the city in the United Arab Emirates faces an existential threat, as the war between the US and Israel and Iran has shaken the foundations of the “Dubai dream” that so many foreigners had bought into.

Iran has set ablaze two tankers in Iraqi waters as it increased attacks on oil and transport facilities across the Middle East

• Iran escalates attacks on infrastructure and transport across the Gulf

• How have you been affected by the latest Middle East events?

An Iranian source is denying the country will allow India-flagged tankers to pass through the vital strait of Hormuz, Reuters is reporting.

The news agency a little earlier quoted an Indian source as saying Iran would in fact allow such tankers to pass through the strait, a key artery for global oil trade.

A preliminary US military investigation has reportedly determined that Washington was responsible for a deadly Tomahawk missile strike on an Iranian elementary school in February that killed scores of children.

According to the New York Times, quoting unnamed US officials and others familiar with the initial findings, the investigation has concluded that the strike on 28 February on the Shajarah Tayyebeh elementary school building was the result of a targeting mistake by the US military planners.

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.
