Much as I want someone to replace Starmer, this decision is not a big surprise, really. Aside from Starmer’s desire for self-preservation, Burnham becoming an MP would have forced a mayoral by-election in Manchester which Labour might well have lost (on current polling, Reform had a slight edge). Burnham had a chance to run as an MP in 2024 without causing that problem and decided not to, so it’s hard to feel too sorry for him.
