The latest Gorton & Denton by-election betting

The Betfair market looks very pleasing for anybody who backed the Greens at 6/1 yet I think there could be some value in backing Labour.
I suspect the infamous, statistically irrelevant, Find Out Now poll has allowed Labour to frame the narrative as a two horse race between themselves and Reform, if the by-election is framed as stopping Reform then Labour could profit, particularly the views of the Reform candidate on those he considers British.
