British Prime Minister Keir Starmer has officially announced his resignation outside 10 Downing Street, bringing an end to a turbulent tenure marked by policy reversals, crashing approval ratings, and deep internal party mutiny.
The emotional announcement on Monday comes less than two years after Starmer led the centre-left Labour Party to a historic landslide election victory in July 2024, which ended 14 years of Conservative rule.
“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,” Starmer said, his voice choking with emotion as his Cabinet and Downing Street staff looked on.
Starmer stated that he will remain in office as a caretaker prime minister until a leadership contest is completed. The process to elect his successor will officially launch in July, with a new leader expected to be installed before Parliament returns from its summer recess in September. With his departure, Britain is now set to install its seventh prime minister in a decade.
Fall of Keir Starmer, rise of Andy Burnham
The immediate catalyst for Starmer’s surrender was last Thursday’s crucial special parliamentary election in Makerfield.
Veteran politician and former Greater Manchester Mayor Andy Burnham won a decisive victory, returning him to the House of Commons.
Burnham is due to be sworn in as a Member of Parliament on Monday afternoon, clearing his path to launch a leadership run that senior party figures believe he is in pole position to win.
While some Labour MPs are pushing for a full leadership contest to heavily scrutinise candidates, others are calling for a swift coronation of Burnham to stabilise the shaky UK markets.
Scandals, U-turns, and electoral collapse
Though Starmer fought aggressively over the weekend at his Chequers country retreat to maintain his grip on power, a quiet mutiny by more than half a dozen of his own Cabinet ministers forced his hand.
Public support for Starmer’s administration plummeted following an array of political crises:
The Mandelson Scandal: Starmer faced severe backlash and an internal revolt in March 2026 after appointing Peter Mandelson—a known historic associate of the late convicted sex offender Jeffrey Epstein—as the UK’s ambassador to Washington.
Electoral Wipeout: In May’s nationwide local elections, the Labour Party suffered a devastating defeat, losing over 1,400 council seats and completely losing control in Wales, while Nigel Farage’s right-wing Reform UK party made massive gains.
Policy Volatility: Constant U-turns on core fiscal promises, including highly unpopular cuts to winter fuel allowances for pensioners, left Starmer with a record-low 74% public disapproval rating.
Adding to the chaos, U.S. President Donald Trump took a pre-emptive jab on Sunday afternoon, posting on social media that Starmer would resign due to failures in energy and immigration policies, effectively pushing the British leader to the door before his official press conference.
Poignantly, Starmer’s resignation arrives exactly one day before the 10-year anniversary of the historic Brexit referendum—the monumental political event that originally triggered a decade of unprecedented leadership churn in Downing Street.
“I will give my successor my full and unequivocal support, knowing that they will inherit a Britain that is far stronger and fairer than the one I inherited two years ago,” Starmer concluded before returning inside Number 10.
