Heathrow third runway calls rejected by government

The transport secretary has insisted the coalition government will stick to its election pledge to oppose the building of a third runway at Heathrow Airport.

Justine Greening said expanding Heathrow was "not right" and other options needed to be considered, including building another "hub" airport somewhere else in the UK.

The row restarted after senior conservative and former environment minister Tim Yeo Prime Minister told David Cameron to decide whether he was a "man or a mouse" over increasing capacity at Heathrow.

On Tuesday evening, with mounting pressure from business leaders, the chancellor George Osborne said ministers accepted the need for greater airport capacity.
