British Prime Minister Keir Starmer is expected to resign on Monday, June 22, 2026 [1].
A leadership change at 10 Downing Street would signal a major shift in the UK government amid ongoing internal turmoil within the Labour Party.
Reports from multiple outlets suggest Starmer is stepping down following a sweeping cabinet mutiny and a broader internal party rebellion [1, 2, 3]. This instability follows heavy losses for the party during the local elections in May [4, 5]. Additional pressure has mounted due to the Peter Mandelson scandal, which further strained Starmer's relationship with his colleagues [4, 5].
While some reports state the resignation is set for Monday [1, 3], other sources describe the situation as a crucial decision for the Prime Minister. The Associated Press said Starmer is facing a choice to either step down or fight a leadership challenge [6].
Internal dissent has reached a critical point within the legislature. Dozens of Labour lawmakers have called for his resignation [6]. The scale of the rebellion suggests that the Prime Minister has lost the confidence of a significant portion of his own party.
Starmer has not officially confirmed the timing of his departure. However, the reports of a Monday exit align with the intensity of the current cabinet pressure [1, 3].

The potential resignation of Keir Starmer reflects a collapse of internal party discipline triggered by electoral failures and ethical scandals. If he steps down, the Labour Party must quickly navigate a leadership transition to avoid a prolonged power vacuum that could destabilize the UK's domestic policy and international standing.
