Heathrow (Third Runway)

I have visited Manston airport, and I can see the argument for its expansion and I recognise that it has a part to play. Indeed, several airports in and around London could help in relieving the expansion capacity problems that we face. However, no one is seriously suggesting that one of those 400 sites could be a substitute hub airport. The hon. Gentleman knows enough about aviation to recognise that we are talking about Heathrow, which is a hub airport and an international gateway very different from the airport that he mentions.
