It is ever more urgent that we investigate the possibility of a long-term solution, in the form of a new and more eco-friendly airport at a site in the Thames estuary - of which you will be hearing a lot more in due course.I wonder what he meant by that. I hope he meant that as London mayor he will back such an enterprise. In the 1990s a company called Marinair came up with an innovative plan to build an airport slap bang in the middle of the Thames estuary. Now is the time for them to dust it off, revive it and spark a real national debate about its feasibility.
But the debate cannot last forever. Heathrow and Gatwick are at bursting point. If London wants to remain a pre-eminent world city it needs airports to match its ambition. If the capacity cannot be provided at Heathrow, Gatwick and Stansted it has to be found elsewhere.
So in 2017 I look forward to hearing the captain of my plane telling us through the intercom: "Ladies and Gentlemen, we're about to land at London's Boris Johnson International Airport..."
Every successful politician leaves a legacy. This can be Boris's!
