This week, Jeremy Corbyn said he was 'sincerely sorry' for the pain that had been caused to the Jewish community by anti-Semitism in 'pockets' within the Labour Party. Alas, his apology wasn't enough to stop protesters – including some of his party colleagues – gathering in Parliament Square on Monday to voice their concerns. Nor were Corbyn's comments enough to dissuade some of his more loyal supporters that allegations of anti-Semitism aren't always an MSM smear designed to keep the Tories in No 10.

So that readers can make up their own mind as to the size of those 'pockets', below is a list which has been compiled detailing alleged incidents on the matter:

1. Corbyn came to the defence of Sheikh Raed Salah, who revived the medieval anti-Semitic 'blood libel' slur that Jews cook with children’s blood. Salah was arrested by British police in 2011 when he was due to speak at an event in the House of Commons - alongside Corbyn. In 2012 Corbyn called Salah 'a very honoured citizen'.

2. Labour Students at Oxford University Labour Club mocked the Jewish victims of the Paris kosher supermarket attack, called Auschwitz a ‘cash cow’, and used the Neo-Nazi slur ‘Zio’, according to extensive testimony from Jewish students. After months of obfuscation, including an NEC decision to not publish a party report that concluded there had been 'some incidents' of anti-Semitic behaviour, Labour’s NEC decided not to discipline the key perpetrators.

3. A Jewish Labour MP, Ruth Smeeth, was sent a 1,000 word death threat from a Corbyn-supporter calling her a 'yid c--t'. The threat followed Smeeth’s decision to walk out of a meeting outlining Labour’s response to anti-semitism because she was accused of working 'hand in hand with the right-wing media to attack Jeremy'. Smeeth then received 20,000 abusive messages and has since questioned whether Labour is still 'a safe space for British Jews'.

4. A Labour council candidate in Peterborough, Alan Bull, shared anti-Semitic material online which claimed that the Holocaust was a 'hoax'. The Labour party was made aware of the posts in 2017, but only suspended the candidate when contacted by the Jewish Chronicle in March 2018. Bull says he has never denied the Holocaust and re-posted the article in question to find out what his friends thought of it.

5. Jeremy Corbyn was an active member of an 'anti-Semitic' Facebook group, ‘Palestine Live’. The group included Holocaust denial, 9/11 conspiracy theories and anti-Semitic slurs. He said he did not see the offensive posts and left in 2015.

6. A former Labour parliamentary candidate in Witham, John Clarke, shared a Neo-Nazi meme saying the Rothschild family has used money lending and Israel to ‘take over the world'. He said the meme 'contained a great deal of truth' and was later suspended.

7. Jeremy Corbyn had a ten-year association with a group which denied the Holocaust. Mr Corbyn was a 'stalwart' supporter of Deir Yassin Remembered, attending events in 2013, with the group’s founder, Paul Eisen, a self-professed Holocaust denier.

8. Jackie Walker, formerly vice-chair of Momentum, said Jews were the 'chief financiers of the sugar and slave trade', criticised security for Jewish schools, and said Holocaust Memorial Day was not 'inclusive' enough. After the comments were made and widely condemned, Corbyn shared a platform and campaigned alongside Walker.

9. Jeremy Corbyn hosted an Islamic cleric in Parliament in 2009, who in 2006 wrote that 'Europe has made political correctness, the cult of the Holocaust and Jew-worshipping its alternative religion'.

10. Nasreen Khan, a Labour council candidate subsequently barred from standing, asked: 'What have the Jews done good in this world?'. She said schools were 'brainwashing us and our children into thinking the bad guy was Hitler' and said 'Jews have reaped the rewards of playing victims'.

11. A Labour councillor in Birmingham, Zafar Iqbal, shared a David Duke video on Facebook entitled ‘CNN Goldman Sachs and the Zio Matrix’. The Labour party accepted Mr Iqbal’s apology and claim that he had have no recollection of sharing this video' – no disciplinary proceedings were enacted.

12. Two Jewish Labour councillors in Haringey resigned, saying it is impossible to be a Jewish Labour councillor due to overwhelming anti-Semitic abuse. Joe Goldberg and Natan Doron reported that 'many members have repeated to me assertions about Jews having big noses, controlling the media and being wealthy', and that a fellow councillor accused Goldberg of 'bagel-barrel politics'. On his resignation, a Haringey Momentum activist tweeted to Goldberg: 'At least [you] will have more time to count your money.' Mr Goldberg said complaints he made to party officials were dismissed.

13. Andrew Slack, a councillor in Chesterfield, was suspended after sharing an anti-Semitic meme of a blood-smeared, hook-nosed Israeli soldier. The meme said 'Israel was created by the Rothschilds'.

14. Bethany Barker, a student activist who introduced Jeremy Corbyn at a 2017 local elections campaign event, described a Kippah as a 'Jew cap' and said Andres Breivik, the Norwegian far-right terrorist, should 'get forced to live in a synagogue'.

15. Pam Bromley, a Labour Councillor in Lancashire, posted links to an antisemitic article entitled 'World War 3: Trump Begins Paying His Homage to Rothschilds,' commenting 'we must remember that Rothschilds are a powerful financial family (like the Medicis) and represent capitalism and big business'. Bromley is still a Labour councillor and no disciplinary action has been taken.

16. Ken Livingstone reportedly said a Jewish journalist was 'just like a concentration camp guard', that Jews vote Tory because they are rich and that Hitler supported Zionism. Despite his attempt to draw a parallel between those who fought for Jewish freedom and those who perpetrated a Jewish genocide, Livingstone was only given a temporary suspension from a party disciplinary panel – a decision Corbyn supported, despite 100 Labour MPs calling for Livingstone’s expulsion.

17. Terence Flanagan, a member of Hampstead and Kilburn CLP, compared a Jewish councillor to Josef Goebbels and, when calling for his expulsion, referred to former Labour donor Michael Foster allegedly as 'the Jewish millionaire'. Flanagan was suspended, but then readmitted to the party after formal written warning.

18. Tim Lezard was offered a job to work at Labour’s Southside HQ, despite tweeting 'I’m thinking of setting up another new campaign group. Either Conservative Friends of Nazis, or Nazi Friends of Israel.' When his tweets were revealed the job offer was rescinded.

Terry Kelly, a councillor in Renfrewshire, wrote that the 'American Jewish lobby is extremely powerful and it has its boot on Obama’s neck' and that the film ‘The King’s Speech’ might not win an Oscar because 'there is a powerful Jewish lobby campaigning against the film because of its historical inaccuracy about Hitler and the anti-Semitism'. Mr Kelly was temporarily suspended in May 2016 before being reinstated a month later.
