Starmer resigns: UK Prime Minister steps down as Labour leader after party revolt, new leader to be chosen by September.
British Prime Minister Keir Starmer has announced his resignation as leader of the Labour Party and will step down as Prime Minister after a successor is chosen, following mounting pressure from within his party over recent weeks. Speaking outside Downing Street on Monday, June 22, 2026, Starmer confirmed that he had informed King Charles III of his decision and requested that the Labour Party’s National Executive Committee establish a timetable for a leadership contest. Nominations for the party leadership are set to open on July 9, 2026, with a new leader expected to be selected before Parliament reconvenes in September. Starmer said he accepted that many within the party no longer viewed him as the best person to lead Labour into the next general election and pledged his full support to his successor during an orderly transition of power.
