David Cameron attacked for delaying Heathrow expansion decision

Labour accuses Tories of dithering to spare mayoral candidate Zac Goldsmith embarrassment, while business leaders say holdup thereatens exports

David Cameron has been accused of letting down British exporters and ducking and diving for political convenience by planning to delay a final decision on whether to press ahead with the expansion of Heathrow airport.

No 10 said there would be a clear decision this week, but declined to say whether this would be the final choice to go ahead.
