Starmer resigns as UK prime minister after Labour revolt, ending two-year tenure amid by-election rout
British Prime Minister Keir Starmer announced his resignation Monday, fighting back tears, after a rival's by-election win triggered a Labour Party mutiny.
Pressure builds on Starmer
Keir Starmer's leadership had been under sustained attack after a series of policy missteps, scandals and dire opinion polls. The prime minister's approval ratings sank to the lowest for any British leader, and the fallout from the Peter Mandelson–Epstein affair, economic stagnation and turbulent relations with U.S. President Donald Trump eroded Labour's standing. On Sunday, Trump delivered a final jab by predicting that Starmer would resign, shoving the British leader toward the door before any official announcement.
The byelection that tipped the scales
The decisive blow came from Andy Burnham's resounding victory in the Makerfield by-election on 19 June. The Greater Manchester mayor defeated a Reform UK candidate, securing a parliamentary seat that makes him eligible to challenge for the Labour leadership. The scale of Burnham's win convinced many Labour MPs to switch their support to him, transforming the internal party arithmetic and leaving Starmer all but certain to lose a formal contest.
Leadership contest timetable
Speaking outside 10 Downing Street, Starmer confirmed he had asked Labour's governing body to set out a timetable to replace him. Nominations will open on 9 July and close at the summer recess on 16 July. A new leader, who will also become prime minister, is expected to be in place before Parliament returns in September. Starmer will remain in office until the contest concludes and pledged "full and unequivocal support" to his successor.

Starmer's emotional farewell
Starmer fought back tears as he described the role as the "proudest moment of my life." He thanked Downing Street staff, the civil service, his wife Vic and his children.
He added that he would now spend more time being "the best husband I can" and "the best dad I can."I want to thank the brilliant Number 10 staff and our country's extraordinary Civil Service who dedicate their lives to public service.
A tumultuous tenure
Starmer, 63, led Labour to a landslide victory in 2024 after 14 years of Conservative rule, but his premiership lasted less than two years. His time in office was marked by failures to deliver on campaign promises, the ousters of senior advisers, criticism of his handling of the Ukraine and Iran crises and the controversial appointment of Peter Mandelson as U.S. ambassador. The resignation will usher in Britain's seventh prime minister since 2016.
Every decision I have taken has been about putting the country I love first. That is why I will resign as leader of the Labour Party.
