Third Heathrow airport runway 'could be built over M25'

A third runway at Heathrow could be built over the M25, the Transport Secretary has said.

It comes after Theresa May's decision to back Heathrow expansion plunged the Conservatives into turmoil, as Cabinet ministers hit out at the move and a prominent MP quit.

Tory supporting councils are poised to support legal action challenging the plans and Foreign Secretary Boris Johnson insisted the scheme was "undeliverable".

Conservative bosses were forced to announce the party would not fight the by-election triggered by Zac Goldsmith in protest over the third runway.

The decision to build a third runway at Heathrow will have a "disastrous impact", an environmental campaigner has said.

Ralph Smyth, of the Campaign to Protect Rural England, said: "Building a third runway at Heathrow would in itself take a huge chunk out of the Green Belt, but creating the biggest airport in the world on London's western edge would have an even more disastrous impact.

"Pressure for extra development would be felt in almost every village from the north of Oxfordshire to the south coast, urbanising and industrialising swathes of our most precious countryside."
