Local elections in London, UK are currently scheduled for May 7, 2026. This market will resolve according to the party that controls the most London borough councils as a result of this election. Control is defined as having more than half of the voting councillors of a London borough council. Any executive positions, like Mayor, will not count. A candidate will be considered an official candidate of a party if they are officially nominated by that party and are registered for the relevant election in affiliation with that party. Independent candidates will not count for any party. This market's resolution will be based solely on the number of councils controlled by the specified party, not any coalition of which it may be a part. In the case of a tie between two or more parties for the greatest number of councils controlled, this market will resolve in favor of the party whose name comes first in alphabetical order, as listed in this market group. Resolution of this market will be based on the results of the relevant London borough council elections, once those results are official. This market may resolve to the listed party as soon as it becomes mathematically impossible for any other party to equal or surpass its number of councils controlled in these elections. If the results of any of the relevant 2026 London local elections aren’t known by April 30, 2027 11:59 PM ET, the winning party will be determined based on the available results up to that point. If none of the results of the relevant 2026 London local elections are known by that time, this market will resolve to “Other”. This market will resolve based on the results of the elections as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the respective council government.
