Good morning. Today’s the day, probably. Keir Starmer is expected to announce that he will step down as prime minister, after overwhelming pressure from Labour MPs to make way for Andy Burnham to become party leader.

This follows the Manchester mayor’s emphatic victory in last Thursday’s Makerfield byelection, where he leveraged his popularity and the prevailing anti-Starmer mood to secure more votes than Reform and Restore combined, cementing his credentials as the man who can take on the hard right in the next general election.

Middle East | High-stakes talks between the US and Iran are expected to continue for the rest of the week in Switzerland, after a tense start that saw Iranian negotiators walk out in protest at a stream of threats issued by Donald Trump on social media.

Prisons | Pet ferrets kept as therapy animals at the UK’s largest children’s prison have been co-opted by managers to kill rats, resulting in a bloody incident and concerns over child and animal welfare.

Tuesday | This day marks the 10 years since the UK voted to leave the EU. A Guardian report analysing the complex legacy of Brexit through boats, bankers and borders is a good place to consider the legacy of leaving the EU.

Tuesday | Also this day, Peter Murrell, the ex-chief executive of the SNP, is likely to be sentenced to prison custody after pleading guilty to embezzling more than £400,000 from the party.

Wednesday | Donna Ockenden will publish her review of Nottingham University Hospitals NHS Trust, Britain’s biggest maternity care scandal.
