Gorton & Denton by-election: background, constituency history and latest betting odds, with Reform & the Greens leading the market.
A high-stakes parliamentary by-election is set to take place in the Gorton & Denton constituency in Greater Manchester in early 2026, triggered by the resignation of Andrew Gwynne, who stepped down on health grounds. Gwynne, a long-serving Labour figure, had represented the area since its creation at the 2024 general election and previously held neighbouring seats for Labour for almost two decades.
Gorton & Denton was formed ahead of the last general election and combined traditionally Labour-leaning communities from Manchester and the surrounding towns. Notional results suggest it was a solid Labour area in previous elections, with the party enjoying large majorities. However, the political landscape has shifted dramatically since 2024, with Reform UK’s surge in local and national polls and the collapse of both Conservative and Labour support in many traditional heartlands.
The by-election has been further complicated by internal Labour Party tensions. Popular Greater Manchester Mayor Andy Burnham sought to stand as the Labour candidate but was blocked by the party’s National Executive Committee, citing strategic concerns about triggering an expensive mayoral election if he were elected MP. Critics have warned this move could damage Labour’s chances in the contest.

Political analysts have highlighted that a Reform victory would mark a seismic shift in British politics, particularly in a seat built from Labour strongholds. The Greens have similarly pointed to tactical voting opportunities, viewing the contest as a “two-horse race” with Reform after Burnham’s exclusion.
