Keir Starmer announces resignation as UK prime minister, paving way for Andy Burnham succession
British Prime Minister Keir Starmer announced on Monday, June 22, 2026, that he is stepping down as leader of the Labour Party and will remain caretaker prime minister until a new leader is chosen, a process he said could be completed by September at the latest. Starmer made the statement outside 10 Downing Street less than two years after leading Labour to a landslide general election victory in July 2024. Andy Burnham, the former mayor of Greater Manchester who recently won a by-election in Makerfield, is widely regarded as the frontrunner to succeed him.
Starmer announced his departure after months of declining poll numbers, a poor showing for Labour in May 2026 local elections, and a direct challenge from Burnham, who won a by-election last week with the stated aim of contesting the Labour leadership. In his statement, Starmer said: "The question my party is asking now is whether I am best placed to lead us into the next general election. I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace." He said he would remain in office until a new leader was chosen, with nominations opening July 9.
Starmer's resignation makes him the sixth prime minister in a decade to leave 10 Downing Street prematurely, following David Cameron, Theresa May, Boris Johnson, Liz Truss, and Rishi Sunak — a sequence of departures stretching back to the 2016 Brexit referendum. The Washington Examiner and CNN both noted this pattern, with CNN framing it as the UK's "seventh prime minister in a decade" counting Burnham's expected succession. Starmer served 717 days in office, according to the Washington Examiner, compared to Liz Truss's record-low 45 days and Cameron's 2,255.
Among the factors cited across sources for Starmer's fall: an early controversy over accepted gifts, a series of welfare-cutting policy reversals that angered Labour MPs, the appointment of Peter Mandelson — who had described Jeffrey Epstein as his "best pal" in 2003 — as UK ambassador to the United States, and a failure to deliver promised economic growth. The AP reported that when documents surfaced in September 2025 showing the depth of Mandelson's ties to Epstein, Starmer fired him, but the damage proved irreversible. CNN described Starmer as having left office as "the least popular prime minister on record."
