Ms Shah said: “The statement referred to by BuzzFeed was neither drafted by me nor approved by me. This was a very personal issue which I felt required a very personal response.

“I had caused the offence, it was right that I wrote my own apology. I sent my final statement to the Labour party for information. At no point was it changed by my party.”

The move would appear to confirm many of the fears of moderate Labour MPs about a growing acceptance of anti-Semitic views in the party.

It emerged last night that a major donor has withdrawn his support amid the escalating scandal surrounding Labour.

David Abrahams, who has donated around £650,000 since the turn of the century, said he did not believe the party leadership was doing enough to tackle the problem following a series of suspensions of members and councillors.

Ms Shah’s statement followed a chaotic 24 hours, which saw Mr Corbyn forced by the party’s general secretary, Ian McNicol, to suspend Ms Shah hours after declining to do so.

The row was started by an entry on social media in 2014 in which Ms Shah said that a “solution” to the Middle East conflict was to “relocate Israel into the Unites States”.
