Story summary

Zack Polanski, a candidate from the Green party, has confirmed he wants to run in the upcoming by-election for the Holborn & St Pancras seat, which was previously held by Keir Starmer. The seat is seen as an important test of the Labour party's strength, and the Greens believe they have a good chance of winning it. However, there may be opposition to Polanski's candidacy from within his own party, with some local Greens pushing for a different candidate who is British Palestinian or has pro-Gaza views. Polanski has been living and working in the community for many years and says he loves the area, which he believes represents "so many of the things that make London so special". He plans to run on a platform of standing up for people struggling to pay their bills. The by-election is an early test of Labour's popularity following leader Andy Burnham's recent success in polls.
