Sir Keir Starmer resigned as prime minister of the United Kingdom on June 22, 2026, during a farewell address in London.

The resignation marks a significant shift in British leadership following a period of internal party instability and mounting pressure from lawmakers.

Speaking outside Number 10 Downing Street, Starmer announced his decision to step down from the premiership [1]. He said that his tenure had reached its natural conclusion, telling the gathered crowd, "My work is done" [2].

Starmer confirmed that Andy Burnham will succeed him as the next prime minister [3]. The transition comes as the United Kingdom faces a period of historic leadership churn. According to reports from CNN and NPR, the country will have its seventh prime minister in a decade [4, 5]. Other reports have characterized the instability as the sixth prime minister in seven years [6].

"I have decided to resign as Prime Minister," Starmer said [7].

The outgoing leader did not elaborate on the specific internal disputes that led to his departure, but the move allows Burnham to take over the premiership immediately to stabilize the government [8, 9]. Starmer's exit follows a pattern of rapid leadership changes that have defined the British executive branch in recent years.

Burnham, previously the mayor of Greater Manchester, now assumes the role of head of government. The transition is expected to focus on addressing the legislative priorities that Starmer left unfinished during his term.

"My work is done."

The rapid succession of prime ministers—reaching seven in 10 years—signals a period of profound instability within the UK's political system. By handing the premiership to Andy Burnham, the government is attempting to resolve internal party friction and restore legislative efficiency, though the frequency of these leadership changes may weaken the UK's perceived stability on the global stage.
