UK Prime Minister Keir Starmer Resigns After Less Than Two Years in Office

British Prime Minister Keir Starmer announced his resignation as Labour Party leader on June 22, 2026, following intense political pressure and a historic slump in approval ratings. Starmer will serve as caretaker prime minister until his party selects a successor, with nominations opening on July 9. His downfall follows a series of policy reversals, a devastating defeat in the May 2026 local elections to Nigel Farage's Reform UK, and a major scandal involving his appointment of Peter Mandelson, whose close ties to Jeffrey Epstein triggered a police investigation. Former Greater Manchester Mayor Andy Burnham has returned to Parliament and is poised to run to succeed Starmer.
