Zack Polanski, leader of the Green Party in England and Wales, is poised to seek election as the Member of Parliament for Holborn and St Pancras in a forthcoming by-election following Keir Starmer’s resignation. Local Green party members have reportedly expressed support for Polanski’s candidacy, with a formal selection decision expected by the end of next week.
Polanski, who has led the Greens for a year but has yet to hold parliamentary office, indicated that the by-election represents a pivotal moment for his party and broader political ambitions. Marking the anniversary of his leadership, he described the contest as a “referendum on ending rip-off Britain,” signaling his commitment to repositioning the party and challenging traditional political dynamics.
Holborn and St Pancras, an urban and ethnically diverse constituency in London with a large student population and a history of engagement with left-leaning candidates, presents both opportunities and challenges for Polanski. The area is known for its progressive electorate, which could be fertile ground for Green policies. However, the seat has traditionally been held by Labour, with Starmer himself having been its MP, making it a difficult contest.
Labour remains confident in retaining the seat. Tulip Siddiq, the current Labour MP for the neighboring Hampstead and Highgate constituency, expressed assurance in her party’s prospects, highlighting Labour’s strong local presence despite setbacks in recent local elections. Labour’s candidate selection is underway, with applications closing imminently and a shortlist expected early next week. Leading contenders include Sagal Abdi-Wali, leader of Camden council and a Somali refugee who has been noted for her ability to connect with diverse communities; Adam Hug, recently displaced from leadership in Westminster council by the Conservatives; Nash Ali, a former Camden mayor; and Rishi Madlani, a former councillor.
The internal dynamics within the Green Party add complexity to Polanski’s potential candidacy. While he enjoys considerable backing among local members, candidate selection ultimately resides with the constituency party, and some within the Greens have voiced differing views on the best approach. Additionally, progressive forces in Holborn and St Pancras remain fragmented. Andrew Feinstein, a former anti-apartheid campaigner and founder of a left-wing party known as Your Party, has called for unity among left-leaning candidates but has not endorsed a particular contender, leaving open the possibility of splintering the progressive vote.
Observers note that Polanski faces significant strategic decisions. His leadership agenda aims to reshape leftist politics, contending directly with Labour and emerging parties, but entering Parliament as a backbench MP could pose challenges to his influence. Moreover, the contest tests the Greens’ ability to convert recent local election successes into national parliamentary representation. Some analysts caution that failure to secure the seat may undermine Polanski’s credibility as leader and raise questions about the party’s future trajectory.
The Holborn and St Pancras by-election, set against the broader backdrop of shifting political allegiances in London and heightened debates over issues such as the Gaza conflict — which have complicated Labour’s positioning — is being closely watched as a gauge of the Green Party’s electoral momentum and the reconfiguration of left-wing politics in the capital. Both Polanski and Labour contend with balancing local concerns and national narratives in a race that could shape the parliamentary landscape ahead of the next general election.
