Lord in Waiting/Government Whip (Lord Lemos) (Lab)

My Lords, Amendment 78 aims to prevent changes to the UK immigration status held by Chagossians and their descendants, regardless of any agreement or treaty between the United Kingdom and Mauritius or any change in the sovereignty status of the British Indian Ocean Territory. Under UK law, as noble Lords noted, Chagossians and their descendants are either automatically British citizens or have a right to apply to be registered as British citizens. As British citizens, they are free to make their home in the UK without being subject to immigration control. The Government have been very clear that the Diego Garcia Military Base and British Indian Ocean Territory Bill will protect British nationality rights, so I give the noble Lord, Lord German, that assurance. The treaty and the Bill make no changes to the citizenship that Chagossians currently hold or to their right to claim British citizenship. As the noble Lord, Lord Cameron, mentioned, this is being debated in respect of other legislation. All Chagossians will remain eligible for British citizenship and free to make their home in the UK should they wish to. The immigration status of Chagossians living in the UK who do not wish to take up British citizenship will not be impacted by the agreement between the UK and Mauritius. In the Government’s view, this amendment is therefore unnecessary and would prevent the UK Government exercising their lawful power to amend or alter the immigration status of those subject to immigration control in the UK—for example, if the basis upon which someone’s immigration status was granted changes, or, as we have debated many times in your Lordships’ House, if an individual is convicted of a criminal offence for which they receive a custodial sentence of 12 months or more. Furthermore—this is the salient point—the amendment would also effectively prevent Chagossians applying to amend their immigration status and prevent them exercising their right to apply for British citizenship, should they so choose. I therefore ask the noble Lord, in the light of my comments and the assurance I have given, to withdraw the amendment for the reasons outlined.
