My Lords, we should remember that President Assad as, also, commander-in-chief of the Syrian forces, presided over the deaths of 200,000 of his own people. He has barrel-bombed them and used chemical weapons. Indeed, a recent report of 16 March suggests they have been used in Idlib. Assad is not the person with whom to negotiate for the solution. We are in negotiation with moderates. I agree with the noble Lord, Lord Green, that it is important that negotiations achieve a peaceful transition in line with the Geneva communiqué. It is that work in which we are engaged.
