My right hon. Friend, who is the Chair of the Defence Committee, makes such an important point. That is why Chivenor is interesting, because it has an airstrip, which is built on a flood plain. Do we want to lose that asset? We saw what happened at Heathrow yesterday. If things actually go in the direction that he suggests, it is important that we choose wisely which parts of our real estate that we close down and which parts we might need in the near or long-term future.
