Former British Health Minister Wes Streeting told the BBC he would be 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 lawmakers which are needed to trigger a challenge, told ​BBC Newsnight that he thought a contest should be initiated sooner rather than later.The Labour Party is waiting to see if Andy Burnham, the Greater Manchester mayor, can win a local election in Makerfield on Thursday to return to parliament, where ⁠he would ‌become the frontrunner in any challenge to Starmer.Read More: UK inflation flat at 2.8% in May"I ​think ​the prime minister should be given some space ⁠and time to reflect over the weekend and I ​think we should see where we are then," ​Streeting said.Starmer has repeatedly said he would fight to keep his job and that a leadership contest was not the right thing for the country. Streeting disagreed."We can't carry on with this uncertainty and paralysis," he said."I would prefer ‌the PM to take a decision on his own terms rather than leave it for me or ​Andy or ​anyone else to ⁠trigger a contest."Read More: How Brexit is estimated to have hit the UK economyStreeting quit last month in protest at the prime minister's record, turning up the heat on Starmer, and leading to speculation ​that a leadership challenge was likely in the coming months.In a further blow to Starmer's authority, the highly respected defence minister, John Healey, resigned last week, accompanied by a scathing critique of Starmer's record in allocating funds to increase defence spending.
