Keir Starmer announced his resignation as British prime minister on Monday, June 22, less than two years after leading the Labour Party to a landslide general-election victory, bowing to months of pressure from MPs and cabinet ministers alarmed at the party’s collapsing standing.
“The question my party is asking now is whether I am best placed to lead us into the next general election,” Starmer said in announcing his decision, acknowledging that the answer within Labour had turned against him.
The immediate cause was the rapid rise of Nigel Farage’s far-right Reform UK and a catastrophic set of local-election results in May, when Labour lost 1,496 council seats and Reform gained 1,453. Starmer had failed both to blunt Reform’s appeal to working-class voters and to hold a progressive base that had drifted away over his positions on Israel and welfare.
His departure clears the path for Andy Burnham, the popular former mayor of Greater Manchester, who engineered a return to the House of Commons only last week. A by-election in Makerfield — triggered when sitting MP Josh Simons stood aside — sent Burnham back to Parliament with 55 percent of the vote, finishing more than 9,200 votes ahead of Reform’s candidate, a stronger showing than expected.
Possession of a Commons seat is what allows Burnham to contest the Labour leadership. Nominations open on July 9 and close on July 16, when Parliament rises for its summer recess; if more than one candidate clears the threshold, a new leader will be chosen by September 1. Candidates need the backing of at least 81 MPs — 20 percent of Labour’s 403 seats — to enter the race.
Two of the most senior potential rivals, Health Secretary Wes Streeting and Deputy Prime Minister Angela Rayner, have signalled they will support Burnham rather than stand against him, narrowing the contest before it has formally begun.
The change at the top will make the United Kingdom’s seventh prime minister in a decade, a churn that began with the Brexit referendum and has run through Conservative governments led by Theresa May, Boris Johnson, Liz Truss and Rishi Sunak before Labour’s 2024 return to power.
Starmer, a former director of public prosecutions who entered Parliament only in 2015, had staked his leadership on competence and stability after years of Conservative turmoil. But sluggish growth, persistent strain on public services and the Reform breakthrough left him unable to translate his commanding parliamentary majority into durable public support.
His successor will inherit a packed and contentious agenda, including a planned second UK–EU summit in Brussels, a proposed ban on social media for under-16s, and Britain’s coordination with allies over the Middle East. Whoever leads Labour next will do so under the shadow of Reform, now the party Downing Street fears most.
