Labour MPs submit motion of no confidence in Jeremy Corbyn
If the motion is accepted it could lead to a ballot on the Labour leader's future.
Two Labour MPs have submitted a motion of no confidence in the party's leader Jeremy Corbyn.
If the motion is accepted it cold lead to a secret ballot of Labour MPs on the Labour leader's future on Tuesday.
Barking and Dagenham MP Margaret Hodge proposed the motion, which was seconded by Stockport MP Ann Coffey.
The motion calls for a discussion at the next Parliamentary Labour Party (PLP) meeting on Monday.
Dame Margaret urged Mr Corbyn to "do the decent thing" and stand down in the way that David Cameron had.
She told Sky News: "The European referendum was a test of leadership and I think Jeremy failed that test.
"He came out too slowly, he was very half-hearted about his attempts to campaign and Labour voters simply didn't get the message."
A spokesman for Mr Corbyn condemned the motion as a "self-indulgent act", although he acknowledged it had been discussed at a post-referendum meeting of the shadow cabinet.
The spokesman said: "It is a time when our party should be uniting to deal with the real issues that face Britain and the real issues that face the people of Britain, and so to create divisions in the party is a bit of a self-indulgent act."
