Labour’s Sagal Abdi‑Wali won the Holborn and St Pancras by‑election, defeating Green Party leader Zack Polanski and keeping the seat for the party that has held it since 2019.

Vote tally confirms Labour hold

The result, announced on Tuesday, shows Labour received 13,500 votes, while Polanski’s Green Party trailed with 9,000 votes, according to the BBC. The margin of 4,500 votes is similar to the 2019 general‑election victory for Labour in the same constituency.

Why Holborn matters

Holborn and St Pancras is a marginal seat that has been a touchstone for the political mood in north London. It was the first constituency in the city to be contested by the Greens in a by‑election, and Polanski’s candidacy was seen as a test of the party’s appeal beyond its core environmental base.

Impact on the Green Party

Polanski’s defeat raises questions about the direction of the Greens. Party leaders have said they will review campaign strategy in the wake of the loss. The result may also influence Polanski’s standing with the party’s membership, as the party faces internal debates about its policy focus and leadership style.

Labour’s prospects in London

Labour’s win keeps its representation in central London at its current level. The party’s leadership will likely use the outcome to argue that its message still resonates with voters in urban constituencies, especially on issues such as affordable housing and public transport.

Looking ahead

The by‑election result will be examined by both parties as they prepare for the next general election. Labour will aim to build on its current standing, while the Greens will look to regain momentum after the setback. The next scheduled parliamentary election is expected in the spring of 2027.
