Welcome to our latest Q&A with a Guardian journalist. Raf will be joining us at 5pm. We have originally asked him to take questions about Brexit as we mark 10 years since the UK’s vote to leave the EU. But … you may well have questions about the last 48 hours as Andy Burnham looks certain to become the next prime minister.

In the meantime, though, Andrew Sparrow is covering another busy and dramatic day in Westminster on the politics live blog and here’s some more on the end of Keir Starmer’s premiership:

As hot weather becomes more common, companies and homeowners are coming up with innovative ways to keep properties cool

When graphic designer Marc Alabaster had a new set of glass doors installed at his West Sussex home eight years ago, he soon realised how they magnified the heat of the afternoon sun.

“The kitchen was 40-plus degrees,” he said. Then he went on holiday to Spain and saw an apartment building wrapped in louvre-like rows of angled fins or blades that shaded the external walls against the sun.

From Gaza to the Peter Mandelson row, his abandoned pledges to the ‘island of strangers’ claim, Starmer’s time at No 10 was truly dismal

Good riddance, Keir Starmer. No sooner had the toppled prime minister wiped away his tears than the solemn guff began. The Labour leader is “principled” and “driven by a deep sense of public service and duty to this country”, said deputy prime minister David Lammy. He showed “the great dignity and integrity that is the mark of the man”, said energy secretary Ed Miliband. “A devoted and dedicated public servant” said home secretary Shabana Mahmood.

No. This was not a decent man defeated by circumstance, a man of duty and integrity who was simply in the wrong job, a principled leader undone by events. This was an unprincipled politician who abandoned promises with as much enthusiasm as he trousered freebies from rich donors.

Whether you fire up the outdoor projector or Netflix and chill in a cool, dark place – let the escapism of cinema be a balm amid the punishingly hot weather

As you will no doubt have noticed, it is quite warm out. Historically warm, in fact. By the end of the week it is likely that the UK will have seen its warmest June day since records began. The Met Office has issued a red warning, recommending that people stay out of the sun entirely. Which sounds an awful lot like code for “stay inside and watch films.”

But which films? It seems only right to watch something that reflects this apocalyptic weather somehow. Here are some suggestions:

How five months in 2016 that encompassed Boris Johnson siding with Vote Leave, Jo Cox’s murder and David Cameron’s resignation shaped the UK’s future

David Cameron, having promised in 2013 that a future Conservative government would offer a referendum on Britain’s membership of the EU, announces the date of the vote: 23 June 2016. The next day, Boris Johnson, then the mayor of London, says he will campaign for leave.

The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”

French PM to hold emergency meeting after heat deaths; ‘London is cooking,’ says UN secretary general

• Tell us: how is the heatwave in the UK and across Europe affecting you?

• Forty drown across France in heatwave and parts of Spain above 30C at night

Italy’s health ministry has declared a red heatwave alert in 15 cities including Milan and Rome on Tuesday and said the number would go up to 16 on Wednesday.

During a red alert – the highest level – the ministry advises people to eat light, stay indoors in the hottest parts of the day and sprinkle themselves with cool water.

Prime minister said to have left Downing Street for secret meeting with his probable successor

Peter Walker is a senior Guardian political correspondent.

The Liberal Democrats are marking the tenth anniversary of Brexit by enjoying their favourite pursuit – being rude about Nigel Farage.

Nigel Farage pocketed a £5m “reward” for the damage he’s caused, while the rest of us are paying for it dearly. When he promised we would be better off, he clearly only meant himself. We are taking over billboards across the UK today to say enough is enough.

Key to a serious Jones run seems to what he makes of Burnham’s economic policies in the coming days - including public control of utilities. And whether Ed Miliband ends up as chancellor.

Estranged husband of Nicola Sturgeon is sentenced for stealing from party over 12-year period

• Montblanc pens to Le Creuset ramekins: police photos show Peter Murrell’s spending habit

• UK politics live – latest updates

Peter Murrell has been sentenced to five years and three months in jail after he admitted embezzling more than £400,000 from the Scottish National party while he was its chief executive.

Murrell stole the money over a 12-year period, splashing out on a luxury motorhome, a Jaguar SUV, Montblanc pens and luxury watches, a set of Lalique salt and pepper grinders and 2kg of coffee granules.

Reform leader says it is ‘purely private matter’ and it is not hypocritical to criticise Keir Starmer for receiving glasses

• UK politics live – latest updates

Nigel Farage has said his £5m gift from a crypto billionaire is “not any of your business” as it was given unconditionally to be spent on anything from Ferraris to gambling on horses.

The Reform UK leader bristled at questions about the £5m gift from the British Thai-based businessman Christopher Harborne in two radio interviews on Tuesday, saying it was “a purely private matter”.
