Zack Polanski said that the outcome of the upcoming Holborn and St Pancras by-election would not determine his authority as leader of the Green Party of England and Wales. According to The Guardian, he also described the contest as “probably 50/50” and “really too close to call.”

The vote was scheduled, according to The Guardian, for the week after 2 October 2026. However, the source does not give the exact date of the poll.

Polanski is aiming to take from Labour the seat previously held by Keir Starmer in Holborn and St Pancras, according to the Guardian’s account.

Describing the electoral race, Polanski said the balance remained uncertain: “probably 50/50 at the moment,” he said, adding that the contest was “really too close to call,” according to The Guardian.

The comments come as, also according to The Guardian, suggestions are circulating that the Green Party’s popularity may have peaked. This is a hypothesis reported by the source, not an established fact based on the available materials.

The central point expressed by Polanski therefore concerns the distinction between his position within the party and the outcome of the individual by-election: according to the leader, the former does not depend on victory in Holborn and St Pancras.

The available materials do not report any election result, nor do they include any further official confirmation that the vote will take place. The only time reference provided by the source is to the week after 2 October.
