This documentary about the journalist’s Alzheimer’s soon takes a turn, as he hears of an unreported mining disaster and goes on the hunt for truth. It’s a dignified tale of a courageous, compassionate man

Jon Snow: A Last Big Story is a valediction that forbids mourning. The hour-long documentary follows the 78-year-old investigative journalist and former Channel 4 news anchor in the wake of his diagnosis with Alzheimer’s disease. During the course of one of his visits with his wife, Dr Precious Lunga, to family in Zambia, he gets wind of a story about a nearby environmental catastrophe involving a Chinese mining company that has gone virtually unreported. And so the documentary opens outwards and we see the man in his element as well as in the grip of what 850,000 Alzheimer’s sufferers in the UK alone, to say nothing of their carers, families and other loved ones, know to be an unforgiving, relentlessly worsening condition.

Early on, Snow asks with interest and no disquiet what the people with cameras around him are doing. “We’re making a film about your career,” his interviewer, Laura, explains. “And who you are now.” “Lumme!” says Snow, the son of a bishop. “How nice!” As they travel in a car together a little later, he leans forward and says politely: “I’ve forgotten your name already … ?” “Laura,” she tells him. “Lovely,” he says, sitting back. “I’m Jon.”

Despite an increase in antisemitism and anti-Jewish feeling in the UK, adult conversions are on the rise

For Elizabeth Arif-Fear, there was no single moment when she realised she wanted to be Jewish. “It was just a journey over time,” she says.

The 37-year-old interfaith activist was born Christian, then converted to Islam and was Muslim for 14 years, before realising that that faith was also not the right fit. Eventually, she found the answer she had been searching for in Judaism. “I feel I’ve finally found God without all the extras,” she says. “Without Jesus, without Muhammad.”

It took a long time for the actor to find her groove – then the smash TV spy thriller changed everything. She talks about getting advice from A-listers, speaking her mind, and why she’s switching to theatre

Sandra Oh bursts into a back room at the National Theatre in London with wayward post-rehearsal energy. The 54-year-old, long one of the most stylish actors in Hollywood, is in brown linen, a herringbone jacket and hat and sunglasses, which she removes before collapsing into a chair and throwing her head forward, arms outstretched, hair splayed across the table. “It’s just the fucking process of it,” she groans. “We just finished our first stagger-through, which if anyone is an actor – it’s early days, so the fact we made it through was great. It’s brutal. We started in the Lyttelton, and it’s interesting to be in that space and to hear verse. You can really hear it. It’s not just about volume or speed. It’s not even solely about intention. You learn so much just being in that space, but the big thing is – sorry.” She catches herself. “I’m just marching on.” And she bellows with laughter.

Oh has been in London for just over a month rehearsing her role as Alice in a modern reimagining of Molière’s Le Misanthrope. It’s a happy return; eight years ago, she was in the capital to film the first of four series of the hit show Killing Eve, which became a phenomenon and changed her life as an actor for ever. Oh played Eve Polastri, the shambolic but brilliant British intelligence agent, who, along with Jodi Comer’s Villanelle, made for one of the best spy capers of recent years. Now, she is playing a novelist – gender-flipped from the 17th-century original, in an adaptation by Martin Crimp – who is fed up with the flattery and dishonesty of the people around her. It’s a deliberate pivot to theatre; last summer, she appeared as Olivia in a starry production of Twelfth Night at the Delacorte Theater in Central Park, New York. In the autumn, she made her debut at New York’s Metropolitan Opera in a production of Donizetti’s comic opera La Fille du Régiment. Unlike the sometimes fraught me-me-meism of screen work, says Oh, working in theatre in general and at the National in particular “is a collaborative thing” – not least, she adds drily, because no one does it for the money. “Everyone has to bring their best and most open selves. And everyone else loves watching everyone succeed.”

Some said Britain’s departure would bring down the union, but countries are still queueing to join

On the night of 23 June 2016, a storm broke out over Brussels. Rain poured and lightning flashed over the European Union headquarters. The next day dawned grey and calm, but the political weather was raging. Britain had voted to leave the EU.

Nigel Farage, then leader of the UK Independence party (Ukip), declared the EU “finished” and “dead”. France’s Marine Le Pen, the Netherlands’ Geert Wilders and Italy’s Matteo Salvini were among the far-right leaders who called for their countries to have a referendum.

Andy Burnham is closing in on Downing Street after a big win in the Makerfield byelection. John Harris and John Domokos take a deep dive into a place where people's lives back up Burnham's insistence that we're living in an economy and society that need radical change – but they also find an infectious spirit of optimism

Manchester, Birmingham and Leeds are experiencing after-hours boom as a result of more lenient rules

London has the earliest council-mandated bedtime of any other city in the UK as a result of policies in nightlife districts that oppose any new bar or restaurant opening past 11pm.

These strict restrictions on pubs and bars are “killing off nightlife” in the capital, experts have said, while other cities including Manchester, Birmingham and Leeds are experiencing an after-hours boom because they have more lenient rules.

Guardian investigation also finds same areas experienced relative decline over same period

Leave-voting areas have seen faster relative growth in foreign workers since the Brexit referendum, a Guardian investigation has found.

Data analysis suggests that the decade since the Brexit vote may not have matched the expectations of many Leave supporters, showing their local areas have also become relatively more deprived over the same period.

Some Labour MPs still want former mayor to face ‘scrutiny’ of ideas through contested leadership race

Allies of Andy Burnham are increasingly confident of a coronation-style transfer of power after the number of MPs backing him for the Labour leadership surged following his byelection victory.

Burnham and his team are understood to have spent the last few days enlisting the support of MPs and ministers, as he prepares to challenge Keir Starmer in the coming weeks.

Counter-terrorism officers investigating as Police Scotland arrest 36-year-old white Scottish man

Counter-terrorism officers are investigating a number of “violent attacks” in Edinburgh on Friday night that injured five men in suspected anti-Muslim incidents.

A 36-year-old white Scottish man has been arrested and police have said there is no further threat to the public.

Unclear if threat has been carried out or if move will jeopardise talks with US scheduled for Sunday

Iran has said it is closing the strait of Hormuz after waves of Israeli strikes in Lebanon in a move that threatens to derail the fragile interim peace deal with the US, signed just days ago.

The Islamic Revolutionary Guard Corps warned ships not to approach the strategic waterway, which before the war carried a fifth of global oil and liquid gas supplies, citing what it called Israeli crimes in Lebanon and a US violation of commitments to establish a ceasefire there.
