Green Party leader Zack Polanski to contest Holborn and St Pancras by‑election

The Labour Party’s leader, Sir Keir Starmer, announced his resignation as Member of Parliament for Holborn and St Pancras, triggering a by‑election in the central London constituency. Shortly after the announcement, Green Party co‑leader Adrian Ramsay confirmed his intention to stand as the party’s candidate for the seat, marking the Greens’ first bid for a Westminster constituency traditionally held by Labour.

The by‑election, scheduled for later this year, will be the first test of voter sentiment since the 2024 general election and could signal shifting dynamics in an area that has long been a Labour stronghold. Ramsay’s candidacy follows the Greens’ recent gains in local elections and reflects the party’s strategy to expand its parliamentary presence. Election officials will set the timetable for nominations, and the contest is expected to attract attention from national parties as they vie for the pivotal London seat.
