My Lords, I congratulate my noble friend on having put the amendment before us. I am sure the Government will take it seriously; I cannot believe that they would do other. I want to make only one point. The convention is terribly important. It is clear time and again that, in our affairs in the UK, it is not yet fully operative. If there are ways in which we have been enjoying the strengthening of its operation by our membership of the European Union, it is doubly important, following any exit from the European Union, that those issues are covered closely by our own arrangements. I am sure that an audit is a realistic and practical suggestion which also deserves attention.
Britain played a very important part, as it so often has in international affairs, in the construction and drawing up of the convention. Many distinguished Conservatives were behind the operation. Because of that commitment—it was not just a matter of getting something on paper; it is how it is actually applied—what my noble friend has proposed and the way she has emphasised it this evening shows that the Government need to give the issue serious attention and to give her the assurances she seeks.
