My right hon. Friend rightly said in his statement that the major legacy of our intervention is that terrorists have been prevented from using Afghanistan as a launch pad for attacks on our streets, and all involved are to be hugely commended for that terrific achievement. But what we have not been able to do is prevent the flow of drugs and the poppy growing, which ends up killing young people on our streets in this country. He rightly says that that represents a generational challenge to us, but may I urge him to attach a top priority, now that the security situation is as good as we could possibly have left it in Afghanistan, to concentrate our efforts on tackling the problem of opium production there? It should be made a top priority for both his Department and the Department for International Development.
