The Conservatives have broken their promise to Surrey residents not to build a 3rd runway at Heathrow, after the government backed the option recommended by the Davies Report today. The Tory U-turn is in direct contradiction to promises made by David Cameron, the former Prime Minister, who said in 2009 that ""The third runway at Heathrow is not going ahead, no ifs, no buts." The Conservative manifesto of 2010 promised no third runway at Heathrow, and Surrey residents have been clear in their opposition to airport expansion at both Heathrow and Gatwick.
