Starmer Resigns

Sir Keir Starmer resigned as MP for Holborn and St Pancras, triggering a by-election.
The race is framed as a progressive, pro-people test of whether a Green candidate can challenge Labour’s dominance and confront entrenched local poverty.
Zack Polanski will stand, stressing housing, NHS and crime issues that reveal stark wealth gaps.
In 2024 Labour won the seat by 11,572 votes, while the Greens received 4,030.

Polanski Runs

Sir Keir Starmer resigned as MP for Holborn and St Pancras in 2024, triggering a by-election.
Local Green activists expressed a split, some preferring a Palestinian-aligned or pro-Gaza independent candidate within the party.
Polanski, excited to become the seat’s first Green MP, noted the by-election date is unannounced.
Andrew Feinstein, 2024 independent runner-up, publicly endorsed Polanski and announced he would not run.

History

Historical Context

In 1997 Caroline Lucas first challenged Brighton Pavilion for the Greens, and in 2010 she became the party’s first sole MP, winning by a 1,252-vote majority. That win made Brighton a Green stronghold through 2015-2019. The 2024 Holborn and St Pancras by-election, where Green Zack Polanski faces Labour after Sir Keir Starmer’s resignation, mirrors this earlier breakthrough.
