So LOM, no answer then to my question of what he said or did that was anti-semitic. Not surprised.

In 2017 Williamson described antisemitism as being "utterly repugnant and a scourge on society, which is why I stand in absolute solidarity with anyone who is subjected to antisemitic abuse". He added that his critics' "accusations of anti-Semitism (against him) were positively sinister" and "highly offensive and hurtful" in suggesting "that I was an anti-Semite myself, yet I have fought racism all my adult life".

In February 2019, Williamson was criticised for booking a room in the Houses of Parliament for a screening of Witch Hunt, a film about suspended party member Jackie Walker, to be hosted by Jewish Voice for Labour. At the same time, a video was published by The Yorkshire Post of him telling a Momentum meeting in Sheffield that the party was being "demonised as a racist, bigoted party", partly because, in response to criticism, the party had "given too much ground (and) been too apologetic", going on to say "We've done more to address the scourge of anti-Semitism than any other political party."

Williamson apologised for his comments saying: "I deeply regret, and apologise for, my recent choice of words when speaking about how the Labour Party has responded to the ongoing fight against antisemitism inside of our party. I was trying to stress how much the party has done to tackle anti-Semitism". On 27 February 2019, he was put under formal notice of investigation, and later that day suspended from the party.

The court case you quote resulted in a ruling that Labour's re-suspension after his readmitance in June was unlawful - a victory of sorts for Williamson although not the way the national press reported it. He was re-suspended in September for very similar reasons to the first time and the court said that disciplinary action must take its course.

Paul Evans (TOBW) wrote in another thread on the anti-semitism crisis in Labour that Chris Williamson on the radio came over to him as very unsympathetic. I can't remember the exact words he used but the impression was that Williamson was strident and not very personable. He is clearly an embarrassment to the Labour leadership who didn't want any defence of the party's actions or push back against those denouncing them. Paul's comments fit with my own impression of Chris Williamson. But I have never seen any evidence of anti-semitic words or actions from him, despite the avalanche of condemnation from the media and his political enemies.
