Zack Polanski, who won the Green Party leadership in September, has seen his party's popularity surge, with polls now showing the Greens just four points behind Labour. This marks a dramatic shift from August, when Labour led by 12 points. If current trends continue, the Greens could overtake Labour in national polls within weeks, a development that would be seismic for British politics.
Polanski's blunt style and effective use of TikTok have boosted his media presence. According to PR consultancy Be Broadcast, he received more broadcast mentions than Liberal Democrat leader Ed Davey between 1 September and 20 October, and nearly as many as Conservative leader Kemi Badenoch. The Greens also garnered the most positive, solution-focused coverage during that period.
The key challenge for the Greens is converting this momentum into sustained support. Historically, smaller parties struggle with perceptions of wasted votes. However, Polanski's rise mirrors that of Nigel Farage, whose Reform UK overtook the Tories in polls last year. For Labour, the threat is existential: many of its supporters vote reluctantly to keep the right out, but could defect if they believe the Greens are viable.
Polanski, a London Assembly member, lacks national political experience but has proven adept at storytelling. He has positioned himself to the left of Labour on issues like wealth taxes, and his party conference speech following a synagogue stabbing was widely praised. While Labour still has a massive organizational advantage, the psychological impact of being overtaken in the polls could be profound.
