There is a suspicion that the weapons and the ammunition used in the shooting of the Israeli ambassador were not brought into the country by any means that would, in any normal circumstances, be detected. It rather looks as though that ammunition may have been brought into the country in diplomatic bags. If that is so, it merely reawakens the concern that this House has expressed on other occasions. I wonder whether my right hon. Friend would be good enough to say whether he thinks that the methods of preventing that sort of thing from happening are adequate? Is he looking into methods of dealing with weapons brought into the country in diplomatic bags?
