Holborn and St Pancras Byelection: High Stakes Voting Begins 2026

Voting has opened in the Holborn and St Pancras byelection, a contest widely seen as a critical gauge of Andy Burnham's ability to energise voters and whether Zack Polanski's Greens can still peel off support from Labour's left. The north London constituency, previously held by Keir Starmer before he stood down as an MP shortly after resigning as prime minister, is traditionally a Labour stronghold. However, the political landscape has shifted, making this byelection a high-stakes event for all parties involved.

Why the Holborn and St Pancras Byelection Matters

This byelection is more than just a local vote; it is a litmus test for the national mood. Andy Burnham, who succeeded Starmer as prime minister in July, is seen as having revitalised Labour. His speech at the party's annual conference last month set out a more ambitious agenda, and a strong performance here would cement his leadership. Conversely, a poor showing could embolden critics within his party.

For the Greens, the contest is an opportunity to demonstrate that their recent surge in the polls was not a flash in the pan. Zack Polanski, who leads the Greens in England and Wales, is standing personally in this constituency, making it a focal point for his party's ambitions. A win here would be a seismic shift in British politics, signalling that the Greens can challenge Labour in its traditional heartlands.

The Candidates and Their Campaigns

Zack Polanski has run a highly energetic campaign, mobilising a large number of supporters to knock on doors. This approach mimics February's Gorton and Denton byelection, where the Greens overcame an even bigger Labour majority to take the seat. Polanski's campaign has focused on progressive policies, appealing to voters who feel disillusioned with Labour's direction under Burnham.

Labour's candidate, meanwhile, has emphasised Burnham's record and the need for stability. The party has poured resources into the seat, aware that a loss would be a major embarrassment. The leftwing independent candidate who challenged Starmer in 2024 is not standing again and has endorsed Polanski, further complicating Labour's path to victory.

Polling and Public Sentiment

Recent polling indicates a tightening race. Shortly after Gorton and Denton, YouGov put the Greens briefly above Labour, on a peak of 21%. However, the most recent equivalent had Polanski's party on 11%, 16 points behind Labour. This suggests that Burnham's leadership has halted the Green surge, but the gap is not insurmountable.

Voter turnout will be crucial. In a byelection, typically lower turnout can benefit insurgent candidates with highly motivated supporters. Polanski's ground game may give him an edge if Labour voters stay home.
