Asked directly whether the Government would stick with its pledge to decide on the contentious issue of airport expansion this summer, he said he could “only rely on the words the prime minster used” on Monday. David Cameron told MPs that Heathrow was one of “a number of decisions that we are going to have to look at in the light of the new circumstances with which we are faced”.  It came as John Holland-Kaye, Heathrow's chief executive, urged Mr Cameron to make a decision in the wake of the referendum result. He said: "Now more than ever, Britain needs to underpin its globally recognised economic strength by delivering privately funded infrastructure projects like a third runway, to protect growth and underpin investor confidence."  Despite Sir Howard's recommendation, the Government has also been considering two alternative proposals to a third Heathrow runway: lengthening one of Heathrow’s existing runways and a second landing strip at Gatwick.  Furthermore, Heathrow now faces the potential obstacle of Boris Johnson, a fierce opponent of a third runway. Mr Johnson is considered a leading contender to become prime minister when the Conservative party selects a new leader by September 2.  Even if he does not succeed Mr Cameron, Mr Johnson is still likely to be an influential figure in government. That could harm Heathrow’s chances of securing a third runway even if Mr Cameron gives it the green-light before he steps down.  The HS2 rail link between London, Manchester and Leeds is another project that observers believe could be threatened by the Brexit shock in Westminster.  The scheme was dealt a further blow today by the NAO, which found that the £55.7bn line faces “cost and time pressures”. But Mr McLoughlin insisted that “HS2 will rebalance our economy and generate colossal benefits for the supply chain” and “is on track”.
The Government is “committed” to expanding airport capacity in the south east, despite the political turmoil caused by Brexit, the transport secretary has said, signalling a decision on a controversial £17.
