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.

Boris Johnson: 'Undeliverable' runway will be stopped

Foreign Secretary Boris Johnson has said a third runway at Heathrow is "undeliverable", adding: "I think it very likely it will be stopped."

The long-time opponent of Heathrow expansion has been given permission to publicly speak out against the Government decision.

Mr Johnson said the project would cause "inevitable degradation" to the quality of life of people under the potential new flight paths.

"A third runway is undeliverable," he said. "The day when the bulldozers appear is a long way off, if indeed they ever materialise."
