I have a lot of constituents writing to me about flights coming into Heathrow at 4 o’clock in the morning. Does the hon. Lady share my concern, and the concerns of my constituents, that more and more special dispensations are being given to break the Heathrow airport night-flight quota? Does she agree that as part of this modernisation all airports in urban areas should be beginning to move towards an eight-hour night-flight ban?
