Boris Johnson: Heathrow third runway 'won't happen'

The Airports Commission has said it is "clear and unanimous" that Heathrow should be allowed to build a third runway.

The Mayor of London Boris Johnson has disagreed with the decision and said it "isn't deliverable".

Mr Johnson was asked on BBC Radio 4's Today programme about previous comments that he'd lay down in front of bulldozers, before a runway was built at Heathrow.
