The Chief Executive of the Antisemitism Policy Trust has revealed that when he submitted a complaint about the actions of a Green Party official he was told it not be taken forward because he was not a member.

Danny Stone spoke about the episode during a Home Affairs Select Committee session on antisemitism on Thursday morning.
Labour MP Chris Murray had asked the panellists – including Dave Rich MBE, head of policy at Community Security Trust; Karen Newman, Vice President of the Board of Deputies; and Russell Langer, Head of Public Affairs at the Jewish Leadership Council – how the current political polarisation in Britain contributes to rising antisemitism.
Stone said an important principle established by Lord Mann during his time as chair of the All-Party Parliamentary Group against Antisemitism was that “MPs should take on the antisemitism within their own parties”.
“It remains an important principle, and it built trust so that, across successive governments, there was faith that this was not a politicised effort and that it was something that we expected parties to take on,” he said.
He added that the rise of newer parties and independent political groupings – both in Parliament and in local government – meant that there needed to be proper reporting systems in place for action to be taken. He also suggested that the Electoral Commission might have a role to play.
He then went on to say the Green Party refused to take forward a complaint he had made on the grounds that he was not a party member.
In June 2024 in response to an article in the Times regarding comments made by party members, the Greens’ then-equalities and diversity coordinator said on X: “There now must to be a smear campaign against them, I wonder why? Maybe our policies or mere presence?”
Stone replied by urging the coordinator to take the report seriously: “I said it at the time of the Corbyn antisemitism crisis & it bears repeating. The Macpherson principles indicate that when people report they are subject to racism, they are treated with kindness and cases investigated with due diligence. We DO NOT claim weaponisation and smear. Of course, any EDI lead would know that.”
The Green Party official then responded to Stone with a series of GIFs, including one image with the words “Free Palestine”.

However, Stone told the committee that when he expressed concern to the party about the exchange, he was dismissed.
“It took six months to get a reply, and I was told that because I was not a member of the party, the complaint could not be taken forward,” he said.
Stone then submitted a subject access request to the party “and was told that there were as many as 5,000 documents with my name on. It then went completely silent.
“In May 2025, I complained to the Information Commissioner’s Office. In December 2025 – it took that long – I was told that the party had probably failed its obligations and had been instructed to respond”, Stone said, adding that he thought the way the Green Party had behaved was “not good enough”.
“Political parties – I don’t care which political party – need to be set up to register these complaints and deal with them for their own sake, as I say, so that this does not become a big political issue. Each political party needs to be set up to take on the problems within their own party,” he added.
The Green Party has been contacted for comment.
