Former UK health minister Wes Streeting is prepared to trigger a Labour leadership contest to replace Keir Starmer as prime minister as soon as next week, urging a speedy end to the "uncertainty and paralysis".
Streeting, who has said he has the backing of the 81 Labour MPs needed to trigger a challenge, told BBC Newsnight late on Tuesday he thought a contest should be initiated sooner rather than later.
But Starmer, speaking at the G7 summit in Evian, repeated on Wednesday that he would fight to stay in his job if a formal challenge was launched against his leadership.
