UK Prime Minister Keir Starmer to resign

LONDON -- Prime Minister Keir Starmer announced on Monday he would resign as the leader of his party and as prime minister, setting the stage for the United Kingdom's seventh prime minister within a decade. "The question my party is asking now is whether I am best placed to lead us into the next general election," he said outside 10 Downing Street. "I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace." Starmer, who had lead the Labour Party since 2020, was elected in 2024. A formal challenge to Starmer's premiership had not yet begun as of Monday, but members of his party have in recent weeks pointed to Andy Burnham, the former mayor of Greater Manchester, as his potential successor.
