Fellow MP Ruth Smeeth, who has suffered antisemitic abuse on social media, said Mr Livingstone “continues to bring the party into disrepute” and had "no place in the party”.
Wes Streeting, chair of the All Party Parliamentary group on British Jews, said the suggestion of Mr Livingstone returning to the party would cause “irreparable damage to the party’s standing and reputation”.
Mr Livingstone had told the Observer that the matter was “dead” and that he had done nothing wrong. If expelled from the party, he would take legal action.
“I did not say Hitler was a Zionist. What I referred [to] was an agreement between German Zionists and the Nazi government in 1933 [the so-called Haavara agreement] and you can’t expel someone for stating historical fact when you have done nothing about those Labour MPs screaming that I was a Nazi apologist and all that garbage.”
