A by-election for the United Kingdom parliamentary constituency of Holborn and St Pancras is scheduled to be held on October 8, 2026, following the resignation of incumbent Sir Keir Starmer.
This market will resolve according to the percentage of valid votes received by the Labour Party candidate in the Holborn and St Pancras by-election.
The percentage will be measured as the number of valid votes received by the Labour Party candidate divided by the total number of valid votes cast in the by-election.
Valid vote percentages will be counted only where the official results attribute them to the candidate standing for the Labour Party. Votes attributed to other candidates or party designations will not count, regardless of endorsements or electoral cooperation.
If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
If the results of this by-election are not definitively known by June 30, 2027, 11:59 PM ET, this market will resolve to the lowest range bracket.
This market will resolve based on the results of this by-election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as published by Camden Council (
