Heathrow

I thank the hon. Lady for giving way. She has mentioned the environmental impact of a third runway at Heathrow, but has she also looked at the impact on jobs if capacity at Heathrow or somewhere else in the south-east is not increased? Some 200,000 people are employed either directly or indirectly as a result of Heathrow, and 1.1 million passengers a year connect into Heathrow via the north.
