Three days after the EU referendum, Hilary Benn was sacked after it was disclosed that he had been organising a mass resignation of Shadow Cabinet members to force Corbyn to stand down.
Several other Cabinet members resigned in solidarity with Benn and by 27 June 23 of the 31 Shadow Cabinet members had resigned their roles as did seven parliamentary private secretaries.
Earlier Corbyn announced changes to his Shadow Cabinet, moving Emily Thornberry (to Shadow Foreign Secretary), Diane Abbott (to Shadow Health Secretary), and appointing Pat Glass, Andy McDonald, Clive Lewis, Rebecca Long-Bailey, Kate Osamor, Rachael Maskell, Cat Smith and Dave Anderson to his Shadow Cabinet.
Just two days later one of the newly appointed members, Pat Glass, resigned, saying "the situation is untenable".

A motion of no confidence in Corbyn as Labour leader was tabled by MPs Margaret Hodge and Ann Coffey on 24 June 2016.
Hodge said: "This has been a tumultuous referendum which has been a test of leadership ... Jeremy has failed that test".
Shadow Chancellor John McDonnell and union leaders including Len McCluskey condemned the motion.

On 28 June, he lost the vote of confidence by Labour Party MPs by 172–40.
He responded with a statement that the motion had no "constitutional legitimacy" and that he intended to continue as the elected leader.
The vote did not require the party to call a leadership election, but was expected to lead to a leadership challenge.
Corbyn was encouraged to resign by Tom Watson and senior Labour politicians including his predecessor, Ed Miliband.
Several union leaders (from GMB, UCATT, the CWU, the TSSA, ASLEF, the FBU, the BFWAU and the NUM) issued a joint statement saying that Corbyn was "the democratically-elected leader of Labour and his position should not be challenged except through the proper democratic procedures provided for in the party's constitution" and that a leadership election would be an "unnecessary distraction".
