British Prime Minister Keir Starmer announced his resignation on Monday, June 22, 2026, after serving less than two years in office. Starmer stated he would remain as caretaker prime minister until the Labour Party selects a new leader, with Andy Burnham anticipated to be a leading contender [1][2].
Starmer’s resignation follows weeks of mounting pressure within the Labour Party. The party experienced poor results in the May local elections, and more than 100 Labour MPs publicly called for his departure. Additionally, several senior ministers resigned, further destabilizing his leadership [1][2].
Health Minister Wes Streeting resigned in May, expressing that Starmer would not lead the Labour Party into the next general election [3]. In mid-June, Defence Secretary John Healey and Armed Forces Minister Al Carns resigned due to disagreements over the Defence Investment Plan [4][5].

Andy Burnham, the former Mayor of Greater Manchester, won the Makerfield by-election on June 18, 2026, securing a seat in Parliament and positioning himself as a likely successor to Starmer [6].
What Is Known
Starmer’s decision to resign was influenced by internal party challenges, including electoral setbacks and ministerial resignations. Andy Burnham is expected to be a strong candidate for the Labour leadership [1][2][6].
What Remains Unclear
The exact timeline for the Labour Party’s leadership election remains unspecified. Additionally, the full impact of Starmer’s resignation on the party’s future direction is yet to be determined [1][2].
