Green Party leader Zack Polanski runs in London by-election for former Prime Minister Keir Starmer's seat

In the United Kingdom, the Green Party weighed postponing its annual conference to focus on the Holborn and St Pancras by-election, where leader Zack Polanski is running. The by-election, triggered by Sir Keir Starmer's resignation, is on October 8. Polanski has campaigned in multiple languages, including Bengali, after being mocked for his Urdu video by London Mayor Sadiq Khan. The contest is seen as a test for Labour under Prime Minister Andy Burnham, with a Green win potentially increasing their MPs to six. The party decided to proceed with both the conference and the campaign.
