Darren Williams, a longtime friend of the Labour leader, is the most high profile party member yet to become embroiled in allegations of anti-semitism.

Williams, who ran both Corbyn leadership campaigns in Wales, “liked” the tweet which also talks of “decent Jews” who apparently aren’t part of the conspiracy. A senior figure in Momentum, he is of the majority now governing every aspect of the party’s administration from candidate selection to the current “democracy review”. On Tuesday he spoke in defence of Mike Sivier at a controversial NEC Disputes Panel which ignored official advice to refer anti-semitism allegations to the National Constitutional Committee.

Last week Hastings and Rye CLP were forced to drop Michelle Harris from their current candidate selection process after it was revealed she claimed that those Jews who had “died with dignity” in the Holocaust would be “horrified by what is done in the name of Judaism”.
