Furious MP Ian Austin used an emergency Commons debate on the night Parliament was controversially suspended to launch a savage attack on Jeremy Corbyn.
Delivering a fiery speech from the Labour benches in which he had sat before quitting the party, the Dudley North MP accused Mr Corbyn of presiding over a party allowing 'racism against Jewish people".
As pro-Corbyn MPs including Liz McInnes tried to drown him out, Mr Austin also lambasted Labour's Shadow Chancellor John McDonnell.
He said: "I left the Labour Party to shine a spotlight on the disgrace it’s become under his leadership and because I regard myself as proper, decent, traditional Labour.
