Zack Polanski scored a resounding victory in The Green Party leadership election on a platform promising bold communication and "eco-populism".

Polanski has had an unorthodox path into politics, previously working as an actor, hypnotherapist and mental health counsellor. But he’s been dogged by a 2013 article in The Sun involving a reporter who claimed he helped her try to boost her bust size through the power of thought.

Born in 1982, Polanski is gay and Jewish, and changed his name at 18 to embrace the identity erased by his family's anglicised surname. His first foray into politics was joining The Liberal Democrats, and he stood unsuccessfully for Camden Council and The London Assembly. He joined the Greens in 2017, and was elected to City Hall in 2021, becoming the party's deputy leader the following year.

In his pitch for the leadership, he linked the climate crisis to inequality and called for radical action to fix it. Now leader of The Green Party, Polanski has vowed to "take the fight to Labour", telling The Labour Party,"We are here to replace you."
