Asked whether it was likely that Mr Corbyn would not be able to stand as a Labour candidate, Sir Keir said: “I don’t know, but at the moment that may be the case.”

At the time the report was released, Sir Keir said he was “disappointed” by Mr Corbyn’s response after he claimed the issue had been “dramatically overstated for political reasons”. It led to Mr Corbyn’s suspension.

Speaking at a Jewish Labour Movement virtual conference a month after the report was published, Sir Keir said: “I can’t tell you how disappointed I was with Jeremy Corbyn’s response. Because the words he used, what he said, coming from the former leader of the Labour Party in response to that report, were just about as bad as you can get.

“Everything in a sense that has followed in the last few weeks follows from those words, and that has exacerbated the pain and the hurt, and we are in a position that I did not want to be in.”
