Story summary

The 2026 Greater Manchester mayoral election, the first using the Supplementary Vote system, follows Labour MP Andy Burnham’s 55 % Makerfield by-election win that created the vacancy.
The poll is set for Thursday 30 July 2026, with registration closing at midnight on Tuesday 14 July.
Labour opened candidate selection on 19 June, closed applications on 21 June, will have NEC draw shortlist and says by-election will cost £4.7 million, a figure it cited when blocking Burnham’s candidacy.

History

Historical Context

The first London mayoral election in May 2000 used the supplementary-vote system, a method later abandoned by the 2022 Elections Act in favor of first-past-the-post. Ken Livingstone won that inaugural contest, where candidates were required to pay a £10,000 deposit. As Greater Manchester prepares its 30 July 2026 mayoral poll, officials are again debating whether to retain supplementary voting or adopt the newer system.
