I wish to pose a question. This goes back to a point that the hon. Lady made about the environmental consequences of flying. When I was a member of the European Parliament—I have harked back to that time on several occasions—British Midland Airways used to keep a slot open by flying a completely empty plane between East Midlands airport and Heathrow. That was not particularly good for the environment, and it certainly did not help the people of the east midlands. I am slightly worried that the new clause would have an unforeseen consequence. I understand why it was tabled, but I am not convinced that it has been thought through.
