I've been sent this report in full by a disillusioned non-Corbynite, and I can honestly say I've rarely read anything more shocking.
The 860 page report is extremely detailed and based on around 10,000 emails, but it's also self-critical about the recent period as well as when Iain McNicol was General Secretary.
This may be why the lawyers were apparently concerned: after all, Labour as a whole is being investigated, not any given grouping.
The report provides evidence of hundreds of complaints, including from JLM, Labour Against Antisemitism and Jewish members including complaints about Holocaust denial and extreme antisemitism, allegedly not being acted on while Iain McNicol was General Secretary.
It also reveals the desperation of Labour officials for their own party to fail electorally, and their genuine horror at any successes, including despondency at Labour's 2017 surge. Their targets included members of Keir Starmer's current Shadow Cabinet.
It includes nasty, sometimes vicious, comments against the left (me included, I'm a big boy, I can take it). It is unpleasant, to say the least.
Why is this relevant? The report claims factionalism impacted the handling of antisemitism and raises very searching questions indeed about the approach to antisemitism before Jennie Formby became general secretary in April 2018.
Most importantly, this report shows that antisemitism must always be taken seriously wherever it is found.
For those who think this report shows that antisemitism wasn't a serious problem: it doesn't, quite the opposite. See the screenshots for examples. It does ask crucial questions about how Iain McNicol’s regime dealt with this problem, and why.
