UK Prime Minister Keir Starmer is expected to announce his resignation from office on Monday, June 22, 2026 [1, 2].
The potential departure of the Labour Party leader marks a significant shift in British governance, as internal party pressure forces a change in leadership mid-term.
Reports indicate that Starmer faces overwhelming pressure from Labour MPs to vacate his position [1, 4]. This movement follows the victory of Andy Burnham in the Makerfield by-election, which has positioned Burnham as a primary candidate to take over the party leadership [3, 4].
While multiple outlets report that the announcement is imminent, the timeline remains subject to dispute. A government source disputed the claims that Starmer will announce his resignation on Monday [7]. However, other reports maintain that the Prime Minister is expected to confirm his departure during the coming day [1, 2].
Burnham's recent electoral success has shifted the internal dynamics of the Labour Party, creating a momentum that has made Starmer's continued leadership untenable for many of his colleagues [4, 6]. The transition would represent a pivotal moment for the party as it navigates its current legislative agenda.
The expected announcement on Monday would trigger a process to determine the next leader of the Labour Party and, consequently, the next Prime Minister of the United Kingdom [2, 5].

A resignation by Keir Starmer would signal a loss of confidence within the Labour Party's parliamentary wing. By shifting leadership to Andy Burnham following a by-election victory, the party is prioritizing electoral momentum and internal stability over the current administration's continuity, potentially altering the UK's policy direction.
