Ken Livingstone was today suspended from Labour in disgrace after plunging the party into a new anti-Semitism storm.
The former London Mayor sparked fury by claiming that Adolf Hitler was “supporting Zionism” before he “went mad and ended up killing six million Jews”.
During a surreal few hours in Westminster, Jeremy Corbyn's close ally also spoke of a “well-orchestrated campaign” by “the Israel lobby” in comments that immediately provoked a wave of criticism.
A Labour spokesman said: “Ken Livingstone has been suspended by the Labour Party, pending an investigation, for bringing the Party into disrepute.”
He was later confronted by furious Labour MP John Mann, who branded him a Nazi apologist and accused him of "rewriting history".
A Labour spokesman said Mr Mann, MP for Bassetlaw, has now been summoned to Chief Whip Rosie Winterton to explain his actions.
Mr Livingstone's suspension came after Labour's current mayoral candidate, Sadiq Khan, led calls for him to be kicked out of the party.
