10 verified7 unconfirmed
British Prime Minister Keir Starmer announced his resignation on Monday, June 22, 2026, less than two years after leading the Labour Party to a landslide general election victory. Starmer said he would remain in office as a caretaker until a successor is chosen. Former Greater Manchester Mayor Andy Burnham, who secured a return to Parliament in a special election last week, confirmed he would seek to replace Starmer and is widely expected to run unopposed. European leaders including Ursula von der Leyen and António Costa paid tribute to Starmer, while the annual EU-UK summit scheduled for July 22 was postponed. Former Prime Minister Donald Trump criticized Starmer over immigration and energy policy. Wes Streeting, a former Health Secretary who had been seen as a potential challenger, announced he would back Burnham’s leadership bid. The transition process includes nominations opening July 9 and closing July 16, with a new leader chosen by September 1 if a contest occurs.
