Zack Polanski: The Rise of the Green Party’s ‘Eco-Populist’ Leader

London, 25 February 2026 – Zack Polanski, the Leader of the Green Party of England and Wales, has become a central figure in British politics as he spearheads a radical shift in the party’s strategy. Since securing a historic 84% of the vote to take the leadership in 2025, Polanski has overseen what commentators are calling the “Zack Polanski effect,” with party membership reaching new heights and polling suggesting nearly half of UK adults are considering supporting the Greens. His leadership is currently defined by a high-stakes by-election in Gorton and Denton and a series of bold, often controversial, policy stances.

Recent Developments and Election Strategy

In the final 48 hours of the Gorton and Denton by-election campaign, Polanski has hit back at what he describes as “vile” and “cheap smears” from the Labour Party regarding the Greens’ drug policies. Polanski has remained steadfast in his advocacy for the legalisation, control, and regulation of all drugs, framing the issue as a public health crisis rather than a criminal justice matter. He recently challenged Prime Minister Keir Starmer to resign over the Mandelson scandal, further distancing his party from the current Labour administration.

Looking ahead to the next General Election, Polanski has indicated he may stand in Walthamstow, a seat currently held by Labour’s Stella Creasy. In a notable move of political solidarity, he has confirmed he will not run against Diane Abbott, whom he described as “wonderful.” His “eco-populist” platform includes a vision for a “world without borders,” radical economic policies aimed at Gen Z voters, and a pledge to reduce the cost of living through green initiatives.

Controversies and Policy Stances

Polanski’s leadership has not been without friction. He has recently faced intense scrutiny over his stance on Zionism. While some reports suggest he backed a “Zionism is racism” motion at a party conference, other recent interviews show him refusing to explicitly declare the term “racist,” leading to accusations of equivocation from various community groups. This tension has been heightened by public discussions regarding his own family’s pro-Israel views.

Additionally, Polanski has defended his professional background following a story in The Sun which he claimed undermined his previous career as a therapist. Before entering politics, Polanski worked as an actor, hypnotherapist, and mental health counsellor—a non-traditional path that he frequently cites as the foundation for his focus on public wellbeing.
