Is Zack Polanski the Left's answer to Nigel Farage?

The Green Party in England and Wales has a new leader and by an overwhelming majority members picked the candidate from the radical left-wing of the party - Zack Polanski. His campaign focussed on poverty and Palestine rather than plants or the planet. He’s a former actor, a member of the London Assembly, though not actually a member of parliament. So, is he now the voice of progressive populism that can take on Nigel Farage and Jeremy Corbyn?
