There will be a by election for the constituency of Makerfield later this year, probably on 18 June. https://en.wikipedia.org/wiki/2026_Makerfield_by-election
Each party resolves to the vote share its candidate gets in the election.
I have added the parties that fought in the general election in 2024, plus Restore Britain and the Official Monster Raving Loony Party, who have both said they will field a candidate. Feel free to add parties who say they will contest the election. If there is no Makerfield by election in 2026, resolves to N/A.
Update 2026-05-29 (PST) (AI summary of creator comment): English Democrats are not standing a candidate and will resolve at 0%.
1,000We now have a full list of candidates for this by election, so I am adding all the candidates. Makerfield by-election candidates announced
