Green Party deputy leadership candidates Zack Polanski, Tyrone Scott, Shahrar Ali and Nick Humberstone

It’s official. The Green Party of England and Wales has now published the full list of candidates in this year’s election for the deputy leadership.

The four candidates are:

Shahrar Ali was deputy leader of the Green Party from 2014-16, serving alongside Amelia Womack. He lost his bid for re-election in 2016, and has since stood in the 2018, 2020 and 2021 elections for the party leadership in which he has received around a fifth of the first preference vote. He also served as the party’s appointed spokesperson for home affairs and for policing. Earlier this year, he was removed as a party spokesperson as a result of what the chair of the party’s executive said were “breaches of the Speakers’ Code of Conduct”. As a result of his removal as a spokesperson, and the criticism he has experienced for his comments on trans rights, he currently has a legal claim lodged against the party over what he alleges is “unlawful discrimination, harassment and victimisation for daring to express my gender critical views”. Ali has said he is standing for deputy in order to “ensure an inhabitable planet for our children” and because “women [are] crying out for a politician to speak plainly on [the] importance of sex-based rights”.

Nick Humberstone stood unsuccessfully for the deputy leadership of the party in 2020, coming fifth and receiving 4.3 per cent of the first preference vote. He has since been a target candidate for the Greens in the local elections in Lewisham, coming less than 200 votes short of being elected to the Council in 2022. Prior to that, Humberstone served on the Young Greens Democracy and Accountability Committee. Humberstone has said he wants to provide “ambitious leadership” for the party in order to secure more Green MPs.

Zack Polanski is a member of the London Assembly, where he sits as chair of London’s Environment Committee. He is also currently the party’s spokesperson for democracy and citizenship engagement. Polanski joined the Greens in 2017, following a brief stint in the Liberal Democrats. He has previously faced criticism for an article published in The Sun in 2013, in which he claimed he could teach women to make their breasts bigger through hypnosis – about which he has since apologised “unreservedly” and stated, “the service highlighted is not a service I ever have or would offer outside of the context of this article.” On his candidacy, Polanski has said, “Every single person in this country needs to know what the Green Party stands for, and we have to win more MPs. It’s as simple as that.”

Tyrone Scott was one of the Greens’ candidates in Dalston in the 2022 Hackney Borough Council elections. While his co-candidate Zoë Garbett was elected, Scott fell short. Outside of electoral politics, Scott is known for his public campaigning, particularly around housing issues and on climate justice. On the latter, he was involved in an action which disrupted the final moments of the Glasgow climate talks, storming the stage and declaring “COP26 has been a failure” before COP 26 president Alok Sharma was due to announce the deal that had been agreed. He also served as campaigns and communications officer for the Young Greens from 2019-20. Scott has said that he wants to “represent a Green Party that fights for all forms of social justice, that secures radical change and builds on our platform to create a real Green Revolution.”

It’s not just a new deputy leader that Green Party members will be electing this summer. They’ll also be electing members of the party’s executive (GPEx). A total of eight posts are up for election this year, and there are 18 solo and job share candidates in the running.
