Now the party is being urged to drop Ali who has made a string of offensive posts on social media accounts that have been deleted in recent days, as a candidate.
As first reported by The Spectator, in November 2024, Ali posted an image on Instagram that showed Donald Trump depicted as Uncle Sam with a Magen David on his hat, along with the caption: “I want you to die for Israel. Because I’m owned by Jews.”
In another post, from July 2024, she shared an image of the world in the stranglehold of a snake emblazoned with the Israeli flag, alongside the caption: “It’s time to cut the head of this snake. #FreePalestine”.
On 26 August 2025, Ali claimed that “England has a government over-represented with Zionists Jews [sic], and it appears they care more for Israel than England,” also branding Prime Minister Sir Keir Starmer, whose wife is Jewish, a “Jewish Zionist”.

In June that year, according to The Spectator, she posted: “The Israeli survivors of the Holocaust are systematically repeating the sins of the Nazis. Mass starvation is cheaper than gas chambers, but no less evil.”
Another post, featuring a cartoon of a Jewish man, read: “Don’t you know the rules? We went through the Holocaust, and now we get to kill everyone, forever!!”
Ali’s social media appears to have been deleted or set to private since the reports emerged.
Last June, Mothin Ali, the party’s co-deputy leader, said it was “brilliant” to share a platform with Ali at an “energising and refreshing meeting”.

Now senior opposition councillors in Lambeth have called on Polanski to intervene.
Claire Holland, leader of the Labour group on Lambeth Council, wrote to Zack Polanski on Thursday expressing concern about Ali’s “openly expressed antisemitic views” and urging the party to withdraw her candidacy.
“It is reported that the only action you have taken since the article was published has been to make Saiqa Ali's Instagram private,” Holland said.
“I ask you urgently to consider withdrawing Saiqa Ali as a candidate in the local government elections on May 7 2026, and publicly to condemn her social media posts in the strongest possible terms.”
“As councillors, we play a pivotal role in our communities, ensuring everyone has, and feels confident in having, equal and safe access to our services, and that each resident has the opportunity to contribute to the economic and social fabric of our borough and enjoy all its freedoms as equal and confident citizens,” she added.
“It is alarming and extremely worrying that you, and the Lambeth Green Party, seek to stand a candidate in our borough with such antisemitic and divisive views. We need to go further and faster in fighting hate crime and racism, not bring it into the Town Hall.”
Holland also questioned Polanski on the Green Party’s vetting procedures both nationally and in Lambeth.
Likewise, Councillor Donna Harris, leader of the Liberal Democrats on Lambeth Council, also wrote to Polanski and Scott Ainslie, leader of the Greens in Lambeth, saying on X that: “Allegations of antisemitism and support for a proscribed terrorist organisation are extremely serious and cannot be ignored.”
In her letter, Harris said, “This raises broader questions about the robustness of candidate vetting, including whether comprehensive social media checks are consistently undertaken and enforced.
“Given the particular concern this raises for the Jewish community in Lambeth and across the UK, it is essential that there is clear reassurance that antisemitism, and all forms of hatred, will be robustly challenged, and that all communities will be protected and respected,” she said.
A Green Party spokesperson confirmed on Friday afternoon that Ali remained a candidate in Lambeth, but added: "This does not represent the views of the Green Party; we are looking into it.”
Ali said: “I apologise for any offence or distress caused to anyone by my social media posts. That was not my intention.
“I unequivocally reject antisemitism in all its forms. My comments were rooted in concern for the humanitarian situation in the Middle East, and I remain committed to speaking with care, responsibility and respect for everyone.”
