Civil Aviation Bill

The hon. Lady makes a good point about arguments for economic benefits and the social and environmental consequences. It is important to bear in mind that the Government always keep those matters under review. The consultation process has just taken place. Some hon. Members imply that there will automatically be an increase at Heathrow after 2012, but they are trying to assess a position that we have not yet reached. The Secretary of State at that time will have to take account of what has happened in the intervening period. That will be important in reaching a conclusion. I stress again the fact that the Government’s move on Heathrow until 2012 is positive—but I accept that, as the hon. Lady said, there is a difference of opinion about the extent of the economic impact and how it is determined.
