Starmer Resigns as UK Prime Minister

Starmer's resignation came after mounting pressure from his party following disastrous local election results and internal dissent.

He conceded that he had lost the confidence of Labour MPs and would step down once a successor is chosen.

Andy Burnham, the former Mayor of Greater Manchester, won a by-election and was immediately sworn in, positioning himself as the likely next prime minister.

The transition marks the seventh leadership change in Britain in a decade, underscoring the nation's political instability.
