Nscale’s AI project still in use as depot ahead of pledged completion date – with planning permission filed after Guardian’s inquiries

• Revealed: UK’s multibillion AI drive is built on ‘phantom investments’

The press releases announcing a gleaming supercomputer on the outskirts of north London depict a glass and concrete building, rising from a tree-lined street. Accompanied by images of glowing blue robot faces, it looks like the centre of a technological revolution.

By the end of this year, that artist’s impression is supposed to be a reality.

Kowtowing to US foreign policy in Iraq and Afghanistan had disastrous consequences. Why are leaders making the same mistake all over again?

Here is the sort of analysis you’re being served up by our esteemed commentariat. Keir Starmer’s positioning on the Iran war, we are told, reveals a prime minister with no political compass. True, but talk about burying the lede. The story here is not Starmer’s lack of political acumen. British involvement in the Iran war is not a policy question on which reasonable people might disagree, like raising a tax here or spending a bit more money there. This is a grave crime.

Yet all the pressure on Starmer seems to arrive from one direction. He “should have backed America from the very beginning”, declares Tony Blair, apparently eager for a successor to emulate his own record of dragging Britain into US-led catastrophes widely condemned as illegal. Donald Trump’s sidekick Nigel Farage, Tory leader Kemi Badenoch and the rightwing press make much the same complaint.

Interpol’s DNA unit is helping bring closure to families of murder victims, whose names may be unknown for decades

In the shadow of Antwerp’s main arena, close to the city’s docklands, runs the Groot Schijn River. It was here that the body of Rita Roberts was discovered in June 1992, floating against the grate of a water treatment plant.

She appeared to have been murdered, but Belgian police were unable to identify her. A tattoo of a black rose with green leaves and initials on her left arm was their only clue.

As a new report reveals career ‘apartheid’ in newsrooms, I and many others wonder if the fine promises will ever bring genuine change

There’s a generally accepted ethical requirement for news organisations to reflect society, both in terms of the content they produce and the people who produce it. Unfortunately, this is just not happening. Look, for example, at the new study released this week by the Sir Lenny Henry Centre for Media Diversity revealing a DEI backlash in British journalism, with one respondent describing their office as an “apartheid newsroom”. Look, too, at the Press Awards, said to showcase “the best of national journalism in the UK”, and notably the individual awards shortlists. Search for the Black journalists in them. You’ll struggle. Diversity was clearly not a priority: several categories, including news reporter of the year, feature only men.

As the head of journalism and strategic communications at Goldsmiths, University of London, this all makes my heart sink.

Mojtaba Khamenei has been chosen to replace his father Ayatollah Ali Khamenei as Iran’s supreme leader, while the country continues to be heavily bombarded by US and Israeli forces. There are concerns the move could lead to a further escalation of war in the Middle East, after Donald Trump warned that Khamenei was an ‘unacceptable’ choice. But as oil prices soar, could the US president be looking for a way out of this war? Lucy Hough speaks to diplomatic editor Patrick Wintour.

Yes, we all know blueberries and kale are good for us. But what about some of the other less well-marketed food heroes that have fallen out of favour?

Think of a superfood. What comes to mind? Avocado? Turmeric? Quinoa? Many of us will have a grasp of the most mainstream so-called superfoods. The ones that have become dietary superheroes thanks to savvy marketing. Larger-than-life in the public imagination, they walk among us with a sheen: blueberries with their polyphenols; kale and its vitamin K; goji berries and all their antioxidants.

But what is and isn’t a superfood is actually down to trends – take the current resurgence of a previously shunned, tragically uncool food: cottage cheese. Beloved by Richard Nixon with pineapple (the Watergate tapes weren’t just illuminating in the ways Woodward and Bernstein hoped for) and a diet-culture favourite in the 60s and 70s, the creamy, tangy cheese curd concoction is back. And there are other supposed superfoods that are just as nutrient-rich, but that marketing hasn’t (yet) brought to our attention. Once a regular part of the UK diet, they have fallen, perhaps unfairly, out of favour. So which foods with serious nutritional chops have we forgotten? Which should we reintegrate?

Turkey, Qatar and UAE intercept missiles from Iran; Israeli military announces strikes against infrastructure across Iran and a Hezbollah-linked group

• Full report: Ali Khamenei’s son Mojtaba chosen as Iran’s new supreme leader

• Tell us: how have you been affected by the latest events in the Middle East?

Donald Trump has said a decision on when to end the war with Iran will be a “mutual” one he’ll make together with Benjamin Netanyahu, the Times of Israel has reported.

It said Trump also claimed in a brief telephone interview on Sunday that Iran would have destroyed Israel if he and Netanyahu had not been around. The US president said:

Iran was going to destroy Israel and everything else around it … We’ve worked together. We’ve destroyed a country that wanted to destroy Israel.

I think it’s mutual … a little bit. We’ve been talking. I’ll make a decision at the right time, but everything’s going to be taken into account.

Footage of attack on Minab compound adds to evidence indicating it was a US strike that killed scores of children

• Middle East crisis – live updates

A video has shown a US Tomahawk missile hitting the Iranian naval base next to a primary school in Minab where more than 168 people, mostly children, were killed – adding to evidence that indicates the US was responsible for the school strike.

The video, released by the Iranian news agency Mehr and geolocated to the site by the investigative collective Bellingcat, shows the missile hitting the Minab compound on the morning of 28 February, when US-Israeli strikes on Iran began.

British chancellor says she will take steps to help families with cost of living as oil prices surge

• Middle East crisis – live updates

Britain is likely to be hit by rising inflation because of the US war with Iran, the UK chancellor has said, as she suggested that a “rapid de-escalation” would be the best protection against a jump in energy prices.

Both Rachel Reeves and the prime minister, Keir Starmer, suggested the government would be prepared to intervene to protect UK households against major cost-of-living shocks as oil prices surged past $100 (£75) a barrel for the first time since 2022.

With oil prices soaring and stock markets falling, economists warn that a prolonged conflict in the Middle East risks knocking growth worldwide and boosting prices

• Middle East crisis - live updates

Oil prices continued to surge on Monday, triggering a stark sell-off across some of the world’s leading stock markets amid growing concern that the US-Israel war on Iran could set the stage for a global economic shock.

The Middle East conflict has sparked an energy supply crisis that could risk driving up inflation and interest rates, according to economists, who believe growth is set to weaken while prices rise. Fears of stagflation – where economic activity stagnates, but inflation increases – loom large.
