The newly elected leader of the Green Party, Zack Polanski, has stated he would require 'very strong arguments' before entering any electoral pact with Jeremy Corbyn's planned new party. Polanski, who secured 85% of member votes in a decisive victory, argued that there is sufficient space on the left of British politics for both parties to thrive without formal cooperation.
Speaking after his win, Polanski emphasised that the Green Party's programme would be more radical than Corbyn's, and any pact would need to be justified. He suggested a more likely outcome would be cooperation over which seats each party targets, rather than standing down candidates. Polanski also rejected the idea that the left is overcrowded, pointing to Labour leader Keir Starmer's response to Nigel Farage's 'toxic tirade' on immigration as evidence of a gap in humanitarian arguments.
Polanski, a self-styled 'eco-populist', promised to mimic Nigel Farage's media tactics to challenge both Reform UK and Labour, stating the Greens would not support a Starmer government. He called Farage a 'charlatan' and declared: 'We are here to replace you.' During his campaign, Polanski had been open to cooperation with Corbyn's new party, but now says it is too early to discuss specifics.
In his victory speech, Polanski urged the Greens to aim for more than 30 seats at the next election, calling for ambition and vision. He appealed to 'politically homeless' voters to join the party. Jeremy Corbyn congratulated Polanski on X, expressing a desire to work together for a fairer world. Labour chair Ellie Reeves also congratulated Polanski but challenged him to clarify his stance on Nato membership, after he suggested Donald Trump's approach made the alliance unfeasible. Polanski clarified he does not advocate immediate UK withdrawal, but only if an alternative European defence alliance can be established.
