Polanski selected as Green Party candidate for Starmer's former seat Green Party leader Zack Polanski has been selected as the party's candidate in the by-election for Sir Keir Starmer's former seat in Parliament. Polanski, who is a London Assembly member, will stand in Holborn and St Pancras on 8 October as he seeks to become an MP. He was voted to be the party's candidate by members of the Camden Green Party ahead of local councillor Hamza Chowdhury. Polanski said the Greens might be the underdog in this election but we have the momentum and we can win. He also spoke of how he made Camden my home when he first moved to London 20 years ago, adding he has lived and worked across Holborn and St Pancras for many of the years since.
