Yeah you can really see Bob Crowe rushing to sign a 'no strike' deal with Boris can't you?? If the Tories get back into Westminster they would probably make a move against the RMT on the Underground but I can't see them doing it before, particular as Johnson isn't looking too good at the moment having today lost his third Deputy Mayor.
