Green Party leader Zack Polanski has 'repeatedly' reposted social media accounts found to have hateful content against Jews and Israel, the Daily Mail can reveal.
An investigation by advocacy group Campaign Against Antisemitism (CAA) found that while the politician did not share the questionable content he has 'amplified' extremist accounts accused of 'peddling antisemitism' to his 206,000 followers.
The posts include accusations that 'Israel's Epstein class billionaire backers spend their fortunes on raping, murdering and eating babies', that Zionists are 'not human, they are lower than vermin' and that the sexual violence inflicted by Hamas terrorists on October 7, 2023 was 'a massive rape hoax'.
Polanski was found to have reposted content from at least six accounts that have come under scrutiny.
The findings come just months after Mr Polanski faced a furious backlash after posting an image of a man wearing a black T-shirt that seemingly showed Nigel Farage's execution.
A slogan on the T-shirt read, 'We're only making plans for Nigel', alongside an image of a guillotine.
Mr Polanski refused to apologise, insisting he had not 'done anything wrong' and had made an 'inadvertent mistake'.
He did however pledge to 'make a commitment to be better on my social media' following the incident in July.

Examples of content found on accounts that Mr Polanski has 'endorsed' by sharing other posts, according to the Campaign Against Antisemitism
Daily Mail has seen evidence showing Mr Polanski reposted content from the accounts in question as recently as last month.
Some of the accounts were found to have shared anti-Semitic conspiracy theories that Jews and Israel control the world.
One wrote: 'But sure, it's an 'antisemitic trope' to suggest Rothschilds and Israel control the world. What a f*cking scam'.
Another said: 'Zionism's capture of the western political and media narrative is so successful that you have to pretend it hasn't happened, or you'll be called anti-semitic.'
One of the accounts directly targeted Jews by stating: 'What did Jews get? The state of Israel was created for you, yet you people are still complain[ing] because nothing is ever enough for you lot.'
Another shared a post that stated: 'From the beginning, the jews have been satanic evil colonisers'.
Some of the accounts were found to have shared anti-Semitic conspiracy theories that Jews and Israel control the world or that attacks against the community were 'false flags'
Two accounts dehumanised Zionists by calling them 'the ugliest people on the planet', while another wrote that 'Israeli citizens *are* parasites STOP APOLOGISING'.
The investigation also uncovered the denial of attacks against Jews.
One said of the events of October 7 that it was a 'lie' and that Hamas had 'mainly targeted the Israeli military'.
They added: 'The kids at the festival got caught in the crossfire and many victims were killed by the Israelis themselves.'
Of the arson attacks carried out earlier this year against four Jewish community ambulances in Golders Green, one said: 'They're calling it the most obvious false flag of all time.'
The accounts also celebrated violence against Israel, with one stating that if Tel Aviv had been flattened: 'I would demand a national public holiday of celebration'.
One of the accounts appeared to express support for Hezbollah, a proscribed terrorist group in the UK, by writing: 'Love it when Iran and Hezb coordinate their missile attacks on genocidal Israel'.
Another shared a post stating 'long live the Resistance!', an apparent reference to Hamas, in response to New York Mayor Zohran Mamdani acknowledging the attacks of October 7.
Some of the accounts which Zack Polanski has reposted from deny there was any sexual violence perpetrated by Hamas, while 'many' were killed by 'Israelis' on October 7, 2023
Jews were also compared to Nazis in one post, in which the author wrote: 'They are addicted to killing. Zionism is a death cult, I mean it literally. The ideology only derives meaning from violence against the untermenschen.'
Last month, CAA formally referred the Green Party to the Equality and Human Rights Commission (EHRC) over the passing of the 'Zionism is Racism' motion. Following the latest incident, it has accused the Green Party leader of being 'in hock to extremists'.
A spokesperson said: 'Zack Polanski may not have shared these particular posts, but we have uncovered how he has repeatedly amplified accounts that peddle vile antisemitic tropes.
'That speaks volumes about the company he keeps.
'Coming hard on the heels of the abominable 'Zionism is racism' motion, it is yet more evidence that he is in hock to extremists, who are now exerting decisive influence over his Green Party.
'There must be repercussions, which is why we have referred the Green Party to the EHRC.'
The Green Party has been contacted for comment.
