Keir Starmer, who resigned as prime minister six weeks ago, has announced he will also step down as the Member of Parliament (MP) for Holborn and St Pancras, triggering a by-election in the London constituency. This decision marks a reversal of his earlier commitment to remain an MP until the next general election. Starmer explained his change of heart by citing a desire to focus on international affairs, though some observers view the move as a politically motivated act that could complicate matters for his successor.
Starmer’s departure has sparked speculation about the upcoming by-election. Historically considered a safe Labour seat since Starmer secured the nomination in 2015, recent election results have suggested growing electoral challenges. In the 2019 general election, Starmer’s share of the vote fell nearly 17 points to below 50 percent. Independent pro-Gaza candidate Andrew Feinstein captured 19 percent of votes, while the Green Party candidate took 10 percent, indicating a notable presence of anti-Labour sentiment that could influence the by-election dynamics.
Attention has turned to Zack Polanski, co-leader of the Green Party, as a potential candidate who might capitalize on this opposition vote. Polanski has expressed a preference for representing a London seat, citing the city as his home for over two decades. While he had previously declined to stand in other constituencies such as Gorton and Denton in Greater Manchester, Holborn and St Pancras is seen as a more plausible target. However, Polanski’s recent political trajectory has been marked by setbacks, including controversies regarding antisemitism and perceived inadvertent support for violence—issues reminiscent of those that troubled former Labour leader Jeremy Corbyn. Additionally, the Green Party’s national polling numbers have declined somewhat, partly due to the rising popularity of the new prime minister, Andy Burnham, who also hails from the Labour Party.
On Labour’s side, potential candidates such as David Miliband have been rumored but have ruled themselves out. Similarly, figures like London Mayor Sadiq Khan and former shadow chancellor Ed Balls do not appear interested in contesting the seat. The party is thus expected to focus on selecting a reliable candidate to maintain its hold on the constituency.
Political analysts suggest that the so-called “Burnham effect” could provide Labour with an advantage in the by-election, as the new prime minister has been credited with tempering anti-establishment sentiments that had previously bolstered protest candidates. While there are concerns about Labour’s vulnerability given the presence of alternative left-wing candidates, the consensus remains that Labour is likely to retain Holborn and St Pancras, provided it fields a strong contender.
Overall, the by-election is shaping up as a test of Labour’s resilience in a constituency that has shown signs of electoral volatility amid evolving political dynamics in London.
