British Prime Minister Sir Keir Starmer has announced his resignation as leader of the Labour Party, triggering a leadership contest that will determine the United Kingdom's next prime minister. According to Antigua News Room, Sir Keir made the announcement in a speech outside 10 Downing Street, stating he was not best placed to lead Labour into the next general election and had informed the King of his decision.
Sir Keir confirmed he has asked Labour's governing body to establish a timetable for his replacement, with nominations opening on 9 July and closing by the summer recess on 16 July. He said a new leader would be in place before Parliament returns in September, and pledged to do "everything" in his power to ensure an orderly transition. He will remain as prime minister until the leadership contest concludes.
In an emotional address watched by supporters, colleagues and Downing Street staff, Sir Keir's voice cracked as he spoke of his priorities beyond politics. Accompanied by his wife Victoria, he said: "When I leave the biggest job in the country, I shall spend more time on the most important job: being the best husband I can to my fantastic wife Vic, who has been a rock by my side through good times and bad; and being the best dad I can to my beautiful children, who are my pride and my joy."
Sir Keir had spent the weekend deliberating over his future at Chequers, the prime minister's official country residence in Buckinghamshire. Pressure from within the Labour Party had mounted following Andy Burnham's victory in last week's Makerfield by-election. Burnham, the former Greater Manchester mayor, is widely regarded as the frontrunner for the leadership after securing a commanding win over his Reform UK rival. He is expected to travel to Westminster on Monday to formally take his seat as an MP.
Former Health Secretary Wes Streeting has also previously stated his intention to enter the leadership race.
Sir Keir was elected Labour leader in April 2020 and became prime minister on 5 July 2024 following Labour's general election victory. His resignation means the UK will have its seventh prime minister since 2016.
Discontent within the party had been building prior to a poor set of election results in England, Wales and Scotland in May. Criticism intensified after Sir Keir reversed course on three major policies within a single month following internal party pressure. His appointment of Lord Mandelson as UK ambassador to the United States also drew scrutiny over his judgement. Lord Mandelson was subsequently dismissed after new information emerged regarding the extent of his relationship with the late convicted sex offender Jeffrey Epstein.
Opening his resignation speech, Sir Keir defended his government's record on employment rights, immigration and child poverty. He also argued he had transformed Labour after inheriting a party that was, in his words, "politically, financially and morally bankrupt."
He said: "The hard work of change was with a singular purpose – not power for power's sake but to change Britain for the better, to build a fairer country with dignity and respect, where everyone is seen, everyone is valued, wealth and opportunity for all not just the privileged few."
Reaction from opposition leaders was swift. Conservative Party leader Kemi Badenoch described Sir Keir as a "terrible prime minister" and criticised his policies, including rises in employer National Insurance contributions. Writing on X, she said: "But the problem isn't just Starmer. Labour MPs only want higher taxes to hand out more benefits. These are Labour's choices and their values, regardless of who is running the party."
Liberal Democrat leader Sir Ed Davey called for systemic change, saying: "This time must be different. It can't just be about changing who's in Number 10, it has to be about changing our broken politics so we can fix our country."
Reform UK leader Nigel Farage demanded a general election, warning: "If Labour thinks it can shove another professional politician into No 10, it has another thing coming." Green Party leader Zack Polanski said the country "needs a bold change of direction", adding that Sir Keir "lost the confidence of the country because of his abject failure to challenge the power and wealth of an establishment."
