Keir Starmer is leaving 10 Downing Street. The British Prime Minister announced he will resign by September, capping a turbulent stretch that saw his grip on the Labour Party loosen week by week until it finally slipped entirely.
The timing is not coincidental. Andy Burnham, the former Mayor of Greater Manchester, won the Makerfield by-election on June 18 with 54.8% of the vote, a result that turned simmering intra-party discontent into a full boil. Burnham’s decisive victory gave Labour’s internal critics exactly the figurehead they needed to push Starmer toward the exit.
How Burnham’s by-election win forced Starmer’s hand
Burnham’s commanding performance in Makerfield prompted senior party figures to begin calling for a departure timeline almost immediately. The expectation was that Starmer would outline his exit plan as soon as June 22, with the actual transition aimed at September, well ahead of the party conference season.
Donald Trump claimed on June 21 that Starmer would resign, citing what he described as failures on immigration and energy policies.
