Prime Minister Sir Keir Starmer is to meet Health Secretary Wes Streeting, one of his potential leadership challengers, on Wednesday morning, as his government faces an attempt by Labour MPs to oust him from the top job.
The meeting comes after four ministers resigned, including prominent MP Jess Phillips who quit as safeguarding minister, and Streeting ally Zubir Ahmed.
More than 80 Labour MPs also urged Sir Keir to stand down, exposing deep divisions over the prime minister's future.
Sir Keir vowed to get on with governing on Tuesday, while his cabinet allies and more than 100 MPs rallied behind the prime minister, warning against a leadership contest.
But the prime minister's authority has been weakened by the Labour revolt, which came after a dire set of election results last week.
