Zack Polanski calls for internal rule reforms to give party leaders greater control over policy after Zionism vote.
Published On 11 Oct 2026
Zack Polanski, the leader of the United Kingdom’s Green Party, has proposed a potential overhaul of his party’s democratic mechanisms, calling for the leader to have larger control over strategic direction.
The appeal came in an article published in The Guardian on Sunday after party members passed a motion declaring that Zionism is racism at their annual conference on October 4 in a divisive vote.

Polanski also failed to grab a parliamentary seat in the wake of the row with Israel in a by-election.
The Labour Party won the election for the parliamentary seat vacated by former leader Keir Starmer in Holborn and St Pancras on Friday, fending off a strong challenge from the left-wing Green Party in a boost for British Prime Minister Andy Burnham.
“Our party democracy must now evolve to meet that – creating wider engagement for members, giving leaders more responsibility to set the party’s strategic direction, and making our processes as robust and accessible as possible,” he wrote.
“Above all, that unity must be deployed in the service of changing this country for the better,” the Green Party leader added.
Criticism over vote on motion
Polanski also replied to the criticisms of him for not participating in the vote on the motion on Zionism.
“I have been asked why I was not present for the vote. The answer is that my priority was fighting a hugely consequential by-election for our party,” he said, adding that he put all his “energy into the race in Holborn and St Pancras”.
He admitted that some members feel “let down” by his decision not to make an appearance there.
The Green Party’s motion, which called for “Palestinian liberation, the right of return, Boycott, Divestment and Sanctions (BDS), and a full arms embargo against Israel” was criticised by Jewish groups, other parties and most Green Party MPs.
After conceding defeat in the fiercely contested by-election, Polanski answered his critics, saying he would stay on as leader.
He was barred from entering Israel after his party backed a motion to define Zionism as racism.
