The Holborn and St Pancras byelection is a pivotal moment for the Green Party, with leader Zack Polanski campaigning door-to-door and expressing confidence in a potential upset against Labour. In a high-stakes contest that will test the electoral strength of both the Greens and Prime Minister Andy Burnham's Labour, Polanski remains defiant despite being the underdog, emphasizing the party's grassroots momentum and recent successes. This race is not just about one seat; it is a barometer for the future of eco-populist politics in the UK.
Why the Holborn and St Pancras Byelection Matters
The byelection was triggered by the resignation of former Prime Minister Keir Starmer, who left parliament after stepping down in June. Labour won the seat in 2024 with a majority of over 11,000, making it a safe seat on paper. However, the Greens are hoping to replicate their surprising victory in the Gorton and Denton byelection in February, which signaled a potential shift in voter sentiment. Polanski, who is not yet formally selected as the Green candidate but is expected to be chosen by local members, argues that the party's message is resonating with voters concerned about climate change, housing, and inequality.
The political landscape has changed since Labour's last victory. Andy Burnham, now Prime Minister, faces his first electoral test since taking office six weeks ago. Critics have noted that Starmer's decision to announce his departure on Burnham's first day in the Commons was a calculated move, but it also created an opportunity for opposition parties to challenge Labour's dominance. The Greens see this as a chance to prove they are a serious force in British politics, not just a protest vote.
Polanski's Campaign Strategy: Door-to-Door and Grassroots
Zack Polanski's campaign is built on personal engagement. He has been knocking on doors across the constituency, listening to voters' concerns and promoting the Green Party's policies. According to Polanski, activists have already knocked on thousands of doors, and the response has been encouraging. The campaign emphasizes local issues such as affordable housing, clean air, and public transport, while also addressing national concerns like the cost-of-living crisis and climate action.
Polanski's style is distinctly eco-populist, combining environmental advocacy with a focus on economic justice. He argues that the Green Party offers a radical alternative to Labour's centrism, which he claims has failed to deliver on its promises. In contrast, the Greens propose bold measures like a wealth tax, green investment, and rent controls, which they believe will appeal to voters in a diverse, urban constituency like Holborn and St Pancras.

Recent Polls and Party Momentum
Despite the Greens' optimism, recent polls show the party has fallen in national support, leading to speculation that it may have peaked during the final days of Starmer's premiership. The Gorton and Denton victory was a high point, but maintaining that momentum has been challenging. Polanski acknowledges the difficulty but remains resolute: "We can win here," he says, pointing to the energy of volunteers and the growing dissatisfaction with the two-party system.
The byelection will also test whether the Greens can break through in a constituency that has historically been a Labour stronghold. Holborn and St Pancras is home to a mix of affluent professionals and working-class communities, making it a microcosm of the challenges facing the UK. The Greens are targeting younger voters and those disillusioned with Labour's record, but they face stiff competition from a well-organized Labour machine.
Comparison: Green Party vs Labour in Key Areas
| Issue | Green Party | Labour |
|---|---|---|
| Climate Policy | Net-zero by 2030, massive green investment | Net-zero by 2050, moderate investment |
| Housing | Rent controls, social housing expansion | Affordable housing targets, but less radical |
| Taxation | Wealth tax on top 1% | Income tax changes, but no wealth tax |
| Public Services | Free public transport, NHS funding boost | NHS reform, but limited funding pledges |
This table highlights the policy differences that the Greens are hoping will sway voters. Polanski argues that Labour has become too cautious, while the Greens offer a more transformative vision. However, Labour's machine is formidable, and the party will be desperate to retain the seat to avoid a symbolic defeat.
