The last of the despised killer bendy-buses is off the streets of London and Guido understands that the first new Routemaster will be on the streets next week. Boris actually promised in his manifesto to put the new bus on the road before the end of his first term. There was much scepticism that the cleaner-greener and, according to the experts, most advanced bus in the world, would see the light of day before Boris has to face the voters next year.

It’s an electric bus (it uses a small diesel engine to generate electricity, when it is needed) and is twice as economical as a conventional double decker at 11.6 miles to the gallon compared to the killer bendies 4.5 miles to the gallon. Boris buses following on from Boris bikes are visible signs of success. Cameron, who promised so much in his manifesto, might be a little discomforted by such an eye-catching public service advance.
