Now the other thread has become devoted to Middle East politics, perhaps we can discuss the original subject here again.

The latest development is that Jackie Walker, previously suspended over allegations of antisemitism but later re-admitted, has been suspended again!

BBC,
"Momentum vice-chair 'suspended by Labour' amid anti-Semitism row"

"Earlier, the TSSA union said it would "seriously reconsider" its support for Momentum if Ms Walker remained in place and the group said its steering committee would meet on Monday to seek her removal.
But a spokesman for Momentum, the left-wing grassroots organisation set up in wake of Jeremy Corbyn's 2015 election as Labour leader, said: "Members of Momentum's steering committee are seeking to remove Jackie Walker as vice-chair of the committee."

It can not be argued that this comes from anti-Corbynites. These are pro-Corbynites.
BBC again,
"Manuel Cortes, general secretary of the TSSA union, which backed Momentum and Mr Corbyn's leadership, said on Thursday he was "deeply saddened that a fellow member of our Labour and trade union family holds such anti-Semitic views" and said she should not be allowed to "remain active within our party".
"I am asking Jackie that in the interests of unity she resigns at once from our party and also as vice-chair of Momentum.
"If she doesn't, both the Labour Party and Momentum need to act to get rid of her at once.
"We would seriously need to consider our union's support for Momentum if she is still in post by this time next week." "
