Core Event: By-election to replace Andy Burnham
Voters in Greater Manchester went to the polls on July 30 to elect a new mayor after incumbent Andy Burnham became Prime Minister on July 20. The election used the supplementary-vote (SV) system: a candidate winning more than 50 % of first-choice votes is declared the winner; otherwise the top two candidates proceed to a second round in which second-preference votes are added. Counting began on July 31, with the result expected that afternoon.
Background & Context
Burnham’s elevation to the premiership created a vacancy that, under law, must be filled promptly. The by-election is the first ever for an English combined-authority mayor and, with more than two million eligible voters, is the largest by-election in British history. Burnham’s “No 10 North” office in the city was cited as part of his pledge to give local leaders greater powers.
Candidates & Stakes
Seven candidates contested the mayoralty:
- Bev Craig – Labour Party, leader of Manchester City Council
- Sian Astley – Reform UK
- Geraldine Coggins – Green Party
- Phil Eckersley – Conservative Party
- Richard Kilpatrick – Liberal Democrats
- Marlon West – Restore Britain (far-right)
- Marcus Farmer – Independent
Labour aims to maintain control of the combined authority ahead of next year’s local elections. Reform UK hopes to convert its strong May 2024 local-election performance into a mayoral breakthrough, while the Greens seek to consolidate a surge that saw them win a parliamentary seat in Gorton & Denton earlier in the year.
Data & Statistics
- Eligible electorate: over 2 million (largest by-election electorate).
- 2024 mayoral election (under first-past-the-post): Burnham secured 63 % of the vote, winning every one of the region’s ten boroughs.
- That contest cost the taxpayer £4.7 million.
- Recent polls (three surveys) show Labour leading Reform UK by an average of nearly 20 points on first preferences and projected to hold well over 60 % in a potential runoff.
- Under the SV system, second-preference votes from Green supporters are expected to flow largely to Labour.

What’s Next
The supplementary-vote count will continue on July 31. If a candidate exceeds the 50 % threshold in first-choice votes, the mayoralty will be decided that afternoon; otherwise a second-round tally of second-preference votes will determine the winner. The outcome will shape Labour’s standing in the region and influence strategies for the upcoming 2025 local elections.
