At the end of his statement my right hon. Friend referred to steps that could be taken if it were found that Saudi Arabia were misusing the arms that we supply. Will he expand on that a bit? The issue has come up before in the Committees on Arms Export Controls. If we supplied a consignment of sophisticated weapons for use in one way and it was used differently, or abused in defiance of the laws of war, what could we do to rectify the situation?
