Deputy Prime Minister Nick Clegg has said the Government will not give the go-ahead for a third runway at Heathrow.
Speaking during a visit to a manufacturing firm in Wallsend, North Tyneside, the Liberal Democrat leader said ministers would stick to the Coalition Agreement which ruled out the expansion.
He said: "We're not going to give the go-ahead to the third runway at Heathrow because we said very clearly as both parties that we wouldn't do so, so we're going to stick to the Coalition Agreement.
"But that doesn't mean we're going to stick our heads in the sand over the aviation debate about capacity in this country and how do we make sure we have those proper connections to economies in Asia and Latin America which are important to our own prosperity and we'll make sure we look at that.
"But there are lots of ways of doing that and we shouldn't just lurch to one solution because one individual MP was to say so.
"My position is very clear - we're not going to give the go-ahead to a third runway at Heathrow. We said that in the Coalition Agreement and we're going to stick to that."
