The motion was proposed by Lubna Speitan, a British-Palestinian artist who, The Telegraph reports, joined the Green Party within the past year from Jeremy Corbyn and Zarah Sultana's 'Your Party'. The paper says she told it she joined to push for the rejection of common standards of antisemitism. After the vote she described its passage as a victory over those who "dehumanise and demonise those who dare to resist their oppressors".
On 6 October 2026 The Telegraph reported that court documents filed in New York in 2015 described Ms Speitan as a "close friend" of Minh Quang Pham, and that she had offered to testify in his defence. Pham, a member of al-Qaeda in the Arabian Peninsula, has admitted planning a suicide bombing of the arrivals hall at Heathrow aimed at passengers landing from Israel or the United States. He was sentenced in the United States to 40 years in 2016 and, after new evidence, resentenced to 44 years in 2025. Asked by the paper whether they remained friends, Ms Speitan said: "Yes, it's still the case." She said he had been "targeted" by "the system" and called the question a "character assassination".
The same report says Ms Speitan has argued that Hamas should not be deemed a terrorist group and has called for Zionists to be "hunted down". The Telegraph says the Green Party told it that it needed time to investigate. We have not seen the court file ourselves; the account above is The Telegraph's, and Ms Speitan's words are as the paper quoted them.
The party's leader, Zack Polanski, did not vote. His amendment to protect Jewish members who attend Zionist synagogues was blocked. Vivien Lichtenstein, who chairs the Jewish Greens, told The Telegraph: "There are certainly some anti-Semites in the party." More than a dozen Labour MPs have reported the party to the Equality and Human Rights Commission over the vote.
