Labour wins Holborn and St Pancras by-election, defeating Zack Polanski

The Holborn and St Pancras by-election was called after former prime minister Sir Keir Starmer stepped down, according to GB News. Labour's candidate was Camden Council leader Sagal Abdi-Wali.

Green Party leader Zack Polanski sought to break Labour's hold on the constituency. Al Jazeera described the Greens' pro-Palestine challenge and reported that Labour had held the seat since it was created in 1983.

The stakes extended beyond the constituency. The New York Times described the election as an early test for Prime Minister Andy Burnham, Starmer's successor.

On October 6, The Independent reported divisions among constituents ahead of Thursday's vote. Its reporting highlighted anti-Starmer sentiment and framed the election as a crucial test for both Polanski and Burnham.

By October 7, expectations around the Green challenge had become more cautious. The Financial Times reported that the Greens were braced for defeat, with bookmakers putting Labour ahead. A month earlier, Polanski had said his party was ready to win.

The same day, The Independent reported that Labour held a clear lead over its nearest rivals in its voting-intention tracker, while cautioning that the London picture might be less clear-cut. That was not a declared constituency result.

Voting took place on October 8. Al Jazeera described the contest as a test of whether Burnham could restore faith in Labour. Once polls closed, The Guardian focused on his ability to unite Labour voters against Polanski's challenge.

On October 9, The Guardian reported that Abdi-Wali had been declared the winner with 12,292 votes. Polanski finished second with 8,928.

Labour has retained the seat. The BBC confirmed that Abdi-Wali defeated Polanski, while The Financial Times reported that the ruling party had seen off the Green challenge in Starmer's former constituency.

The declared totals put Abdi-Wali 3,364 votes ahead of Polanski. The result preserves Labour's long-standing hold on Holborn and St Pancras, but the supplied coverage does not give turnout or a complete breakdown of votes for every candidate.
