Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

I thank noble Lords for their speeches. A host of amendments, as we have heard, have been tabled in relation to citizenship rights. Some of them come from a bit of a misunderstanding of what Clause 4 does. I hope that I can explain the detail of what the Bill will mean. If it is not enough, I am very happy to write a letter and put it in the Library, because it is detailed and a little bit complicated. If that would be helpful, that is something I am happy to do. Let me have a go at explaining it all properly this evening and that may suffice. Clause 4 makes provisions related to British nationality as a consequence of the dissolution of the British Indian Ocean Territory. These provisions are essential to ensure that the existing entitlements the Chagossians have to British citizenship remain unchanged. This clause also amends the British Nationality Act 1981 to reflect that BIOT will no longer be a British Overseas Territory, and as a result no future claims to British Overseas Territory citizenship can be made on the basis of a connection to BIOT. This will not result in any change to the existing British nationality status that any Chagossian currently holds; this remains protected. Any Chagossian who currently holds British Overseas Territory citizenship retains it. Current routes to British citizenship will also continue to exist with their original expiry dates for application. This clause is vital in order to protect Chagossians’ rights to continue to obtain British citizenship. Seeking to delete the clause would be to play politics with this right. I turn to the amendments tabled. Amendment 4 is a good example of an amendment that I would gently say is somewhat misconceived in its intent. Chagossians born on the Chagos Archipelago already automatically hold British Overseas Territory citizenship and British citizenship. This amendment would therefore seek to require the Secretary of State to bring forward legislation that would apply to anyone of any nationality born on the Chagos Archipelago once it is no longer a British territory. The Government are clear that, as BIOT will no longer be an overseas territory, it will no longer be possible to make a new claim for British Overseas Territory citizenship. Instead, the Bill preserves Chagossians’ ability to claim British citizenship. Whether a Chagossian has British Overseas Territory citizenship or not will have no bearing on their ability to claim British citizenship under their bespoke citizenship route.
