Keir Starmer resigns as UK prime minister after Labour revolt

Resignation announcement

Keir Starmer stood outside 10 Downing Street on Monday morning and, his voice choking with emotion, told the nation he would resign as Labour leader and prime minister. He said he had informed King Charles III of his decision and would stay on until the party selects a successor. Nominations open on 9 July and close when Parliament breaks for summer recess on 16 July. If a contest is needed, a new leader will be in place by the time MPs return in September.

The question my party is asking now is whether I am best placed to lead us into the next general election. I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace.

Pressure from within

Starmer’s departure follows weeks of mounting calls from Labour MPs for him to stand aside. The trigger was Andy Burnham’s victory in a special parliamentary election last week. The Greater Manchester mayor ran explicitly to challenge Starmer for the leadership, and his win gave Labour lawmakers hope that a more popular figure could reverse the party’s slide. Burnham is due to be sworn in as an MP on Monday and is the clear frontrunner to become the next prime minister.

The Mandelson scandal and policy U-turns

Anger inside Labour had been building for months. Starmer’s government performed a U-turn on welfare cuts and faced backlash over the firing of Peter Mandelson as ambassador to the United States. Mandelson was dismissed in September 2025 after details of his ties to Jeffrey Epstein emerged; he was later arrested on suspicion of misconduct in public office. Hundreds of pages published on 1 June revealed that Mandelson had told a minister Starmer “lacks verve, as does the Cabinet as a whole.” Conservative leader Kemi Badenoch called Starmer’s claim that he was unaware of the risks “completely preposterous.”

Electoral collapse

In May, Labour suffered catastrophic local and regional elections. The party lost control of the Welsh Parliament, recorded its worst-ever Scottish result, and shed more than 1,200 council seats in England. Those defeats emboldened Burnham and convinced many MPs that Starmer could not lead them into the next general election.

What comes next

If Burnham faces no challenger, he could become Labour leader and prime minister soon after nominations close on 16 July. Wes Streeting, who quit as health secretary last month in protest at Starmer’s leadership, has said he will run if there is a contest. European Commission President Ursula von der Leyen praised Starmer’s legacy, writing on X that “European and Ukrainian security is stronger because of you.” US President Donald Trump, speaking on Sunday, said he wished Starmer “the best.”

It can take many leaders years to grow into the statesman you became in just two years.

Starmer’s defence of his record

In his resignation speech, Starmer listed achievements: an economy growing faster than peers, wages rising faster than inflation every month since he took office, the fastest fall in NHS waiting lists in 17 years, the biggest defence spending uplift since the Cold War, and half a million children lifted out of poverty. He said he had inherited a party that was “politically, financially and morally bankrupt” and proved that a Labour landslide was possible. Britain will now get its seventh prime minister in a decade.
