I’m Zack and I am running for leader.

The Labour Government is failing. The planet is burning.

People are looking for somewhere to turn. Nigel Farage and his billionaire mates don’t have any real solutions.

It’s time to rise up.

We need bold action and bold leadership now. And that’s why I’m standing to be the leader of the Green Party.

The Green Party is the party of the popular movement. It’ll take all of us to win. It’s time to rise up.

Endorse Zack for Green Party Leader today.

Let’s grow the movement for bold action and real change.

Bold

Labour’s repeated failures have opened the door to far right fascism and climate denial. Green Party policies are needed now more than ever.

We’ll be absolutely clear about what we stand for, and against. Every person in this country will know that the Green Party is a party of environmental, racial, social and economic justice. Our party must be as diverse and dynamic as the communities we wish to represent.

Leadership

I’ll be a leader who cuts through the noise. A leader who takes clear action. A leader who won’t compromise on our values, and a leader who champions others. I’ll keep listening, and building our next generation. I’ll keep standing with our members and growing this movement from the ground up.

After attending hundreds of rallies and campaigning with countless organisations, it’s clear that people need to know that the Green Party is the party of the popular movement. It’ll take all of us to win.

Now

It’s time to step beyond slow, incremental change - and think big. We know how to win. We’ve elected 4 MPs, 3 London Assembly Members and over 850 councillors.

We can get millions more votes, keep winning, and build community power. Now is the time for the Green Party to realise our potential. Now is the time for ambition.

Not next year, not in five years. Now.

Endorsements

I'm Zack Polanski

Deputy Leader of the Green Party and a London Assembly Member, elected in 2021 & re-elected in 2024.

I chair London’s Environment Committee, where I’ve led work on air pollution, water quality, climate adaptation and environmental justice - and I’ve held the Mayor to account on everything from green jobs, policing reform and workers’ rights.

Before politics, I worked in community theatre (“Theatre of the oppressed”) with a focus on amplifying marginalised voices - and also did lots of jobs in the gig economy from working in prisons, schools, nightclubs and lots of hospitality! I’m Jewish, gay, born in Salford, studied in Aberystwyth and now live in Hackney.

Since joining the Greens in 2017 and becoming a local party chair - I’ve campaigned across the country, supported our candidates, and spoken up for people and planet on national media - even in the toughest spaces. I’ve worked closely with migrant care workers fighting for a living wage, climate activists demanding justice, and unions calling for dignity at work.

My politics is about tackling inequality. Providing a voice for the marginalised to hold those with excess wealth and power to account.
