Heathrow will submit third runway proposals to the government this summer, pledging to use UK steel and boost growth, the airport has confirmed.

Its chief executive, Thomas Woldbye, will formally spell out plans for a third runway to follow a multibillion-pound upgrade of the London airport’s existing terminals and facilities, in a speech at the British Steel plant in Scunthorpe on Wednesday.
