A Nationality & Borders Bill to ensure those descended from individuals born in the British Indian Ocean Territory be allowed to register as British citizens received royal assent in April 2022, with people of Chagossian descent now able to apply to become a British Overseas Territories citizen (largely due to the efforts and support of former MP, Henry Smith).
Henry says that the UK government ceding of this British Indian Ocean Territory to Mauritius, against the will of most islanders is a betrayal of Chagossians, who have not even been offered a vote. I agree. These Chagos Islands were never a part of Mauritius - they were just administered from Mauritius in the French colonial era. Unfair, unnecessary and unwise.
