The defection of Christian Wakeford to Labour has put a spring in the step of the left-wing party. Apparently it marks the start of their revival. Give it two years and Keir Starmer will be waving from the steps of Number 10.

That’s one scenario. A more likely one is that the good people of Bury South will unseat Wakeford at the next general election as Labour suffer another humiliating defeat.
