Greens Lead Gorton and Denton By-Election Betting

UK betting sites have priced up the Gorton and Denton by-election, with the Green Party installed as 1/2 favourites ahead of polling day on February 26.

Last month's resignation of Labour MP Andrew Gwynne has triggered the contest in the South Manchester seat, but what might once have been a routine Labour hold has rapidly become a nationally watched political test.

The race dominated headlines when Greater Manchester mayor Andy Burnham signalled he wished to stand, only to be blocked by Labour’s National Executive Committee which was a decision that has fuelled wider debate about internal party tensions.

With discontent simmering inside the governing party the by-election now carries significance well beyond the constituency boundaries.

Bet365's latest market gives the Green's a 66% implied probability of winning this by-election.

History of the Seat

In 2024, Labour secured 50.8% of the vote, making it one of just 70 seats where the party achieved an outright majority. However, that represented a dramatic fall from an estimated 67.2% in 2019.

The 16.5-point drop ranked among Labour’s ten worst performances in the North West. Nearby seats including Manchester Rusholme, Manchester Central and Manchester Withington also recorded double-digit declines.

Those figures explain why bookmakers have installed the Green Party as clear favourites, implying a 66.7% probability of victory.

Reform UK Positioned as Main Challenger

Reform UK, priced at 12/5, carry an implied probability of 29.4% and are seen as the primary challenger.

With Matt Goodwin standing for Reform, the party will hope to capitalise on dissatisfaction within both Labour’s traditional base and broader anti-establishment voters.

The relatively short odds suggest bookmakers believe Reform could mount a serious challenge particularly if turnout dynamics favour motivated protest voters.

What the expert says...
When you see a seat drift from a 16-point majority decline and ongoing party tensions, bookmakers price volatility into the contest. The Greens at 1/2 reflects both local performance trends and national mood.
