Tory leader David Cameron has ruled out an airport in the Thames Estuary in a television interview.
The estuary site, touted as an alternative to Heathrow and the subject of an ongoing feasibility study commissioned by London Mayor Boris Johnson, is officially not part of Conservative policy.
Cameron told the BBC: “It’s not our policy”. But he gave little encouragement to campaigners for expansion at Heathrow, saying “We don’t want to see the third runway at Heathrow and we can stop that from happening. We want to see instead high-speed rail and a proper rail hub at Heathrow, so that all those flights… that serve places that could be met by rail, all of those will be met by rail. That’s our policy.”
