The Staggers 2 September 2014 Boris Island plans are rejected, but is this really a blow for the Mayor? A proposal to build a new airport in the Thames Estuary is to be rejected in an apparent blow to the Mayor of London. But could it help him? The airport expansion plan seems to have flown over the Mayor of London's head. Photo: Getty Sign UpGet the New Statesman's Morning Call email. Sign-up The BBC is reporting that the plan for airport capacity expansion in Britain – building a new island airport in the Thames estuary – is to be rejected by Howard Davies’ Airport Commission. It is thought to be “too risky” and the “logistical challenges” are too great. The Thames estuary option is known as “Boris Island”, because it is the pet plan of the Mayor of London, who has been backing such a proposal throughout the highly politicised debate about the state of Britain’s aviation and airport capacity. The debate is tied up with opposition to building a third runway at Heathrow, which is thought by many now to be the preferred option of the Commission, and for which the CBI has effectively come out in support, saying a single, larger-hub airport was “critical”. So what does this mean for the Mayor of London? His aviation adviser, Daniel Moylan, has stated: "Airports policy has been stalled for nearly five decades, ricocheting like a billiard ball between Heathrow and Gatwick… "We have only one opportunity to break out of that but it seems the Commission has taken us back to the same old failed choice." Johnson himself has written in the Telegraph that, although his support for “Boris Island” meant backing the single-hub option, a category which Heathrow also falls under, he still will not be supporting the expansion of Europe’s busiest airport: There is no government in the Western world that would even contemplate an act so self-defeating, so short-termist, and so barbarically contemptuous of the rights of the population. That is why all three main parties have correctly ruled out expansion of Heathrow airport, in the form of a third runway. So it is mystifying and depressing to learn that some in Whitehall want to use the cover provided by Sir Howard Davies to effect a colossal U-turn: by announcing that this option is back on the agenda – for consideration post May 2015. The fundamental problem with Heathrow is that it is situated in the western suburbs, so that unlike any other major hub airport it requires planes to land by flying over the heart of the city. The answer is not to keep compounding the mistake, but to look at a new site. Johnson has been on a roll over the summer, announcing his intention to stand as an MP in 2015, and choosing his prospective seat, Uxbridge and South Ruislip. However, if the possibility of championing the Thames estuary option is now out of the window, perhaps it gives Johnson a chance to distance himself from the airport expansion debate, therefore saving him from bashing one of the main employers of his potential west London constituents. › Is a Commons vote a better way of taking Britain to war than the Royal Prerogative was?
