My hon. Friend is right to say that a UN investigation is taking place into the circumstances surrounding the missile. We are certainly concerned about where the parts for that missile might have come from, and that could indeed involve a breach of the arms embargo. We have offered the UN all our technical expertise because it is essential that the incident is fully investigated, and it is unfair to cast aspersions if they are not correct. It is also essential to get to the root of this and, above all, to stop the smuggling getting in. That is part of the key to improving humanitarian access.
