I mean, yes, M.Gove was supposed to run B.Johnson's campaign. He suddenly popped up and decided to have a go for himself. And? B. Johnson could still have run, could have found someone else to run his campaign (how about whoever ran his campaign when he ran for mayor; or whoever ran D. Cameron's?). M. Gove and B. Johnson could just have run against each other (and T. May). I don't understand why he quit (unless the whole thing was pre-planned, of course.) Can anyone shed light on this?
