Zack Polanski has been elected leader of the Green Party of England and Wales in a decisive victory, promising a bolder, more radical approach focused on social and environmental justice amidst a shifting political landscape.
Zack Polanski, a long-time environmentalist and self-described “eco-populist,” has been elected leader of the Green Party of England and Wales in a decisive victory. Securing 20,411 votes, he overwhelmingly defeated the joint leadership bid from Green MPs Adrian Ramsay and Ellie Chowns, who together received only 3,705 votes. Polanski’s election marks a clear shift towards a bolder and more radical direction for the party, with a sharp focus on social and environmental justice.
Polanski, who has been vegan for about a decade following a prior decade as a vegetarian, has woven his environmental ethics closely into his political platform. His longstanding commitment to veganism resonates with his broader agenda of sustainability and animal welfare, reflected in his previous collaborations with advocacy groups such as Viva! to champion plant-based initiatives in public institutions. Earlier this year, Polanski contributed to “A Cruelty-Free Manifesto For London,” proposing key measures to tackle climate change, food poverty, and public health, including urging Mayor Sadiq Khan to adopt plant-based meals by default in City Hall and schools.
The Green Party under Polanski intends to position itself as a stronger left-wing alternative amidst the shifting political landscape in the UK. With traditional parties like Labour perceived to be moving towards the centre or right, the Greens have gained ground on local councils, holding 859 seats across 181 councils and making significant gains in recent elections. Public opinion data suggests that nearly half of potential Green voters are motivated by the party’s climate policies, while others are drawn to its broader progressive stance. Polanski himself has indicated that some Labour MPs disillusioned with their party’s direction are considering defecting to the Greens, further signalling the potential for the Greens to reshape the left-of-centre political space.
In his victory and subsequent statements, Polanski emphasised urgency and ambition, asserting the need for the Greens to become a “bold mass-membership political force” capable of challenging major parties. He voiced a commitment to build a “green left” that does not leave anyone behind, highlighting social issues such as opposition to the two-child benefit cap and cuts to disability benefits. Polanski also expressed openness to collaborating with Jeremy Corbyn’s planned breakaway party, signalling a willingness to unite progressive forces. His leadership vision seeks to directly challenge the current UK government, which he and others say is mishandling climate and social policy at a time when 84 percent of Britons acknowledge climate change and nearly 70 percent attribute it primarily to human activity.
Polanski’s rise comes as climate concerns intensify in the UK, and political disillusionment grows. Amid this backdrop, his campaign promises a more radical Green Party—one that could redefine the country’s environmental and social agenda and present a credible alternative to existing political binaries.
