I can give my right hon. Friend a categorical assurance that we are already in dialogue with the countries and that we will take great care to ensure that we do everything we can to help at the other end, in their airports. We already co-operate closely. To be absolutely clear, this is not a question of singling out countries; we would never embark on such a process. The decisions are taken purely and simply on the basis of what we believe the risks are and where we believe we need to take steps to protect United Kingdom citizens. It is no more and no less than that.
