Starmer’s announcement on 1 September 2026 that he will stand down as MP has triggered an imminent by-election in the Labour-held seat. National polling shows Labour support falling sharply in London while Green backing rises, creating a competitive environment where several candidates from Labour, the Greens and other parties remain closely matched on Polymarket. Party selections are still fluid, local ward results and candidate announcements have yet to clarify frontrunners, and historical by-election volatility in urban seats keeps implied probabilities compressed. Further separation is likely once official nominations close and the first major campaign events or fresh constituency polling emerge.
