The row over whether there will be a third runway at Heathrow continues to rumble on.
London Mayor Boris Johnson, who opposes any Heathrow expansion and favours a new airport in the Thames Estuary, fears that the cabinet reshuffle signals a shift in policy by the government.
However, in Prime Minster's questions David Cameron said he won't break a manifesto pledge of no third runway at Heathrow.
But there are fears that the policy may change if the Tories win the next election and change their manisfesto plans for the next parliament.
London Mayor Boris Johnson has told reporters he is still against expansion at Heathrow yet fears a "u-turn" in Government policy after yesterday's cabinet reshuffle.
