Well said Skipness. I don't think I've ever read anything quite so offensive and inaccurate on the site as the previous replies.
The most vocal opponents of airport expansion and major infrastructure development are white middle class Britons, particularly those living in West London under the Heathrow flight path and in Justine Greening's constituency. All of whom are vital for Boris's hopes for re-election.
Boris has no interest in anything other than his own venality. He's given London nothing except a load of annoying bikes (admittedly quite nice for tourists but useless for most commuting Londoners), a new, expensive and pointless and, as yet, untested Routemaster and a cable car. All flashy and eye-catching, especially with his name attached (as in Boris Island). All at the cost of the poorest commuters in London whose fares have risen out of all proportion and at a time of recession. Meanwhile Boris says it's time to stop banker bashing. By contrast, all the major transport infrastructure projects (Overground renewal expansion, bus route expansion and Crossrail) were initiated by his predecessor.
The only future Boris believes in is his own, at the expense of anyone else.
