My Lords, the noble Lord has great insight on these matters and I agree with him. We are looking at how we can further constrain Iran’s ability to provide such ammunition to countries such as Russia, including through stopping of some of the supply chains. But the noble Lord will know from his own experience that the destabilising effect of Iran—particularly on situations of conflict such as Yemen, where the supply of weapons continues—continues to this day, although through direct co-operation we have had many interventions.
