The negotiations were conducted state to state. Regrettable though it may be, it is a fact that the Chagossians were not party to that, and the noble Lord, Lord Purvis, is right to remind us of it. The Chagossians have been terribly treated since their forced removal all those years ago. My own view is that it is better and fairer to the Chagossians to be clear that, as long as that base is there on Diego Garcia, there will be no ability for them to resettle that island. That is the fact of the situation that we are in, and to give any hope of anything otherwise would be irresponsible and a mistake. But, as the noble Lord says, there will be a process, and the involvement of both Houses of Parliament will be needed as we put the treaty before them and make the appropriate legislative changes that are needed for this deal. As the noble Lord says—and I look forward to it—the voices of Chagossians will be heard through their representatives in this House and in the other place.
