By Matt Chorley, MailOnline Political Editor Boris Johnson today launched a furious attack on a government adviser for rejecting his dream of a brand new four-runway airport in the Thames Estuary. The London Mayor said the rebuttal of his Boris Island plan meant the debate about how to increase flights capacity in and out of Britain had been set back 'by half a century', and claimed the report would simply 'gather dust on a shelf in Whitehall'. But he insisted the plan was not dead, as it emerged Sir Howard Davies's commission will now consider just three options - two additional runway plans at Heathrow and one at Gatwick.
