Is a Jeremy Corbyn run for London Mayor locked in? You’d have to assume the Mamdani success would make it too tempting for him not to go for, and if it’s a four-way split he must be the favourite. Scary: our city could get a *lot* more decrepit and dangerous than it is right now!

Looking at this list from Ladbrokes I think Corbyn has a more plausible route to become mayor that people who according to Ladbrokes have a better chance of winning than Corbyn.

I can see Corbyn’s brand of politics appealing to London in 2028 so at 25/1 I feel a trading bet is in order but I understand why punters might want to swerve this bet.
