• Cameron put off decision until after London Mayoral election
  • Heathrow supported by two-thirds of Labour and Tory MPs

Most lawmakers say a third runway at London’s Heathrow is the preferred method of expanding U.K. airport capacity, according to a survey commissioned by Heathrow.

The ComRes poll of 150 of Britain’s 650 members of parliament, conducted as Prime Minister David Cameron again delayed the decision, found 84 percent said the U.K. needed an extra runway in the south east of England. Two-thirds of those from both the governing Conservative and the opposition Labour parties chose Heathrow as the best place to expand.

Cameron was attacked by business groups last month when he ducked the decision again, putting it off until after London’s Mayoral election in May. The Conservative candidate, Zac Goldsmith, is an opponent of Heathrow expansion.

ComRes interviewed 150 lawmakers online and by paper self-completion questionnaire between Nov. 12 and Dec. 16.
