Sacked Momentum leader Jackie Walker went to a party training event on anti-Semitism "looking for a fight", says another prominent supporter of Jeremy Corbyn.
Walker was removed from her role as vice-chair of Momentum and suspended from the Labour party after leaked footage showed her saying she had not found a definition of anti-Semitism she could "work with."
She also questioned why Holocaust Memorial Day does not encompass other genocides during an anti-semitism training event, which ran parallel to the Labour party conference in Liverpool.
Aaron Bastani, co-founder of Novara Media - an outlet which supports Mr Corbyn - told Julia Hartley-Brewer her comments were "rather ill-judged" and have "deflected away from what was I think a rather good conference.
"She went [to the anti-semitism training event] basically looking for a fight. She had to go to the meeting because if she didn't people would say she's stonewalling them. She should have gone there, sat through it and left.
"Whether or not her behaviour has been anti-Semitic, I think her behaviour has been unbecoming of somebody who holds office for a political organisation."
