There is a phrase for that: “White Wash”
It is highly imperfect, but it shows the low-water mark of actual evidence of anti-semitism in the party (as requested by the OP), and it doesn’t say there is no problem, it says there is definitely a problem, and details how to start fixing it.
Can someone point me in the direction of some actual evidence for all of this? I keep hearing the accusation and im trying to decide if this a real issue or a nasty stitch up.
The answer is yes, according to the Labour Party itself.
What the report doesn’t address is whether senior Labour figures, including Corbyn, are directly or indirectly responsible for the toxic environment described in the report. And that will always be a matter of opinion, possibly coloured by political animus.
