If Boris doesn’t stand again, which almost everyone is assuming, it’s quite hard to see how the Labour candidate isn’t going to become Mayor. Lord Coe would be an interesting runner, but he’s shown no sign of wanting to get back into politics. We’ve seen a bit of money for George Galloway at 25/1; I could just about imagine him making a run-off, but surely he wouldn’t win a second round against a competent Labour alternative.
As things stand, Sadiq Khan would be a very bad result for Ladbrokes, as he’s been backed down from 33/1.
