The Green Party has suspended anti-Israel activist Tony Greenstein from the party, citing his “documented history of antisemitism, including recent terrorism charges.
Greenstein was a founding member of the Palestine Solidarity Campaign. He was also formerly a member of the Labour Party before his expulsion in 2018 over allegations of antisemitism. The Labour Party’s disputes team was then granted a two-year restraining order against Greenstein in December 2021 after he harassed them.
Greenstein also received a nine-month suspended prison sentence in September 2023 after attacking an Elbit Systems factory with Palestine Action. He was also charged with a terrorism offense under the Terrorism Act 2000 for tweeting his support of Hamas on 15 November 2023. Hamas is banned in the UK.
He then joined the Green Party in March 2026.
According to exclusive details revealed by The Canary, Greenstein’s suspension was approved by a vote of 11 to 1.
The Electronic Uprising then leaked an email from Greenstein to the Green Party questioning his suspension on April 16.
“I am not surprised you have suspended a prominent Jewish anti-Zionist,” he wrote. He blamed “the Corbyn playbook” and said, “Accusations of antisemitism in the Green Party have begun to mushroom.” Greenstein has vigorously defended Corbyn from claims of antisemitism in the past.
'Zionism is racism' motion
Greenstein also said he “predicted” that lies and smears would begin against him after he weighed in on the Green Party’s "Zionism is Racism" debate. This, as previously covered by The Jerusalem Post, involved a motion that would have ruled Zionism as racism within the party.
The motion was, however, sabotaged via filibustering at the recent party conference and therefore was never voted on – to Greenstein’s chagrin. He soon after wrote an article called “The only form of racism that matters is Zionism racism.”
Greenstein did acknowledge that he has an upcoming trial date on August 18 under the Terrorism Act 2000, but said he is pleading “not guilty.”
“There is no basis to my suspension,” he said, adding that the party is “acting on behalf of supporters of the Gaza Genocide.”
Greenstein has a history of making controversial statements.
Just a few days ago, on April 16, he responded to a tweet by Israeli journalist Noa Magid asking people to remember Maya Puder, who was murdered by Hamas on October 7. Greenstein reshared it with the words “I prefer to remember the thousands of children you’ve killed and starved in Gaza, not the settlers who killed them.”
He frequently spreads conspiracy theories, such as the "greater Israel" theory, and also frequently calls Israelis Nazis or Hitler.
On October 15, 2025, he tweeted that “Hamas ‘terrorism’ pales in comparison to that of the Irgun and the Zionist terrorist groups.” He also denies Hamas’s atrocities on October 7, including rape.
The Post reached out to Greenstein and the Green Party for comment.
Other candidates post antisemitic content online
Despite Greenstein’s suspension, accusations of antisemitism against multiple other Green Party members and candidates persist.
Last week, The Spectator revealed that two Green candidates are terror supporters.
The first is Ifhat Shaheen, a Green council candidate for Stoke Newington, who defended the October 7 attacks, suggested that Israel is harvesting organs from Palestinians "to help alter [the] DNA of Zionists to claim land," and asked whether "Zionist funding" was behind the racist Tommy Robinson marches.
The Spectator then revealed that Saiqa Ali, a Green council candidate in Lambeth Council, posted a picture of a masked fighter, holding a rifle and a string of bullets, and wearing what appears to be a Hamas headband alongside the words "Long live the Resistance."
She also wrote on Instagram in August 2025 that “today England has a government overrepresented with Zionist Jews.”
Claire Holland, leader of the Lambeth Labour Group, wrote to Green Party leader Zack Polanski saying that “these public posts range from sharing antisemitic conspiracy theories about the 9/11 terror attacks to promoting age-old antisemitic tropes and making offensive, antisemitic statements directly about the Holocaust and our government being ‘over-represented with Zionist Jews.’”
“I note, with regret, that there has been no statement from the Lambeth Green Party, or national Green Party, or yourself as leader, condemning these abhorrent, racist views. Your party, locally and nationally, has been totally silent on this at the time I am writing to you. It is reported that the only action you have taken since the article was published has been to make Saiqa Ali’s Instagram private.”
Just a few days ago, The Spectator revealed a third: Sabine Mairey, a Green candidate for Clapham Town Ward in Lambeth, south London, posted a video to her Facebook page with the caption, “Ramming a synagogue isn’t antisemitism. It’s revenge.”
Scores of other candidates have also been found to post antisemitic content online.
A spokesperson for the Green Party told the BBC last week that there is a “clear distinction” between “vocal criticisms of Israel and antisemitism.”
