Britain's newly announced leader of the Green Party, Zack Polanski, speaks following the announcement of the results of an internal leadership election, at a media event in central London on September 2, 2025. Britain's Green Party elected a self-styled "eco-populist" as its new leader on Tuesday, as the group seeks to gain traction by exploiting dissatisfaction with the Labour government among left-wing voters. Zack Polanski, a former actor, wants to make the Greens as noisy on the left as Nigel Farage's anti-immigrant Reform UK party is on the right as British politics fractures into a multi-party system.
