In a letter to JLM, Mr Mann said: "(Attendees include) those who say that I am ‘loyal to a foreign power’ and ‘paid by the Jews’. I will be celebrating their attendance by referring them for expulsion."
Mr Mann, who chairs the All Party Parliamentary Group on antisemitism, reiterated his call for Jewish Labour MPs be automatically re-selected as canddiates in the next election, in the face of threats of de-selection by pro-Corbyn party members.
He added "the brutality and the consistency of the racism" directed against Jewish Labour MPs Luciana Berger, Dame Louise Ellman, Ruth Smeeth and Dame Margaret Hodge "demonstrates that the Labour Party is now becoming an institutionally racist party, with several thousand openly racist members all claiming to act in the name of Jeremy Corbyn".
"Labour stands at a crossroad. A failure to tackle this insipid racism will mean that the party no longer deserves to exist and will slowly and painfully die," he said in his letter.
