Monday briefing: What’s next for no-drama Starmer as his ‘political challenges’ pile up?

Keir Starmer is expected to announce his resignation as prime minister on June 21, 2026, following significant pressure from Labour MPs to cede leadership to Andy Burnham. This development follows Burnham's decisive victory in last Thursday's Makerfield byelection, where he capitalized on his popularity and a widespread anti-Starmer sentiment to outperform both Reform and Restore parties. His win positions him as a strong contender to challenge the hard right in the upcoming general election.

Meanwhile, high-stakes negotiations between the United States and Iran are anticipated to persist throughout the week in Switzerland. The talks commenced under a tense atmosphere, exacerbated by Iranian negotiators temporarily withdrawing in response to a series of threats made by Donald Trump via social media.
