Zack Polanski, the Green party leader, has been selected as its candidate for the Holborn and St Pancras byelection scheduled for October 8, 2026. According to official announcements, the seat became vacant in September 2026 when former prime minister Keir Starmer announced he was leaving parliament. Polanski secured the nomination following a local party hustings on September 10, beating local councillor Hamza Chowdhury. The announcement was made the following morning at Kings Place in Camden.
The byelection arrives as local political dynamics shift in the constituency. Polanski stated that the Greens are underdogs in the race, noting that the party made substantial gains during the local elections in May by increasing their footprint on the council from one councillor to 10. Despite those gains, Labour holds a significant advantage, having won the seat with a majority of more than 11,000 votes at the 2024 general election. On Wednesday, Labour selected Camden council leader Sagal Abdi-Wali as its candidate.
Political Context and Campaign Stakes in Holborn and St Pancras
Abdi-Wali framed her candidacy around her personal history in the area. She stated that the community welcomed her family as refugees and gave them hope, expressing gratitude for the opportunity to build a life there while serving as a councillor, school governor, and community activist. Meanwhile, Green party figures have emphasized the grassroots nature of their campaign. Hannah Spencer, the MP for Gorton and Denton, announced Polanski’s candidacy by acknowledging Labour’s institutional advantages, including financial support from fossil fuel lobbyists and gambling industries alongside a large campaign machine.
Did You Know? Zack Polanski stated during his campaign launch that he first lived in the Holborn and St Pancras constituency when he moved to London 20 years ago, and noted that his original barber is still located there.
Campaign dynamics may also be influenced by national policy decisions during the race. According to industry insiders, some within the Labour party are concerned about upcoming oil and gas announcements. The government is expected by industry sources to greenlight the Jackdaw gasfield as soon as next week, while any decision regarding the contentious Rosebank oilfield is anticipated to be delayed until after the byelection takes place.
Candidate Visions and the Path to October 8
Polanski has outlined a platform focused on lowering energy bills, pushing for affordable housing and rent controls, reducing wealth inequality, and opposing new North Sea drilling. At his candidate announcement meeting, he argued that his party has genuine momentum, pointing out that weekend canvassing efforts allowed volunteers to deliver leaflets across the entire constituency in just a few hours. He emphasized that the contest represents a clear race between the Green party and Labour.
Expert Insight: Local by-elections in safe Westminster seats often test national government policy implementation against local organizing capacity. The timing of upcoming energy infrastructure decisions, such as North Sea licensing, places environmental policy directly into the center of a campaign where both major challengers and incumbents must navigate voter sentiment on climate action and cost-of-living pressures.
Before securing the nomination, Polanski competed against local councillor Hamza Chowdhury, who argued during the selection process that the constituency did not need an MP who arrives only for an election campaign and departs afterward. With candidates now locked in, both parties are mobilizing their bases ahead of the October polling date.
