Vincatassin was one year old when he was evicted from the Chagos Islands. His parents were not married and so ended up on separate islands. Vincatassin went with his paternal grandparents to Mauritius where he was forced to live in poverty.
Vincatassin is opposed to Olivier Bancoult's Chagos Refugee Group as "they want Mauritian sovereignty over the islands. That is something we cannot negotiate. We believe that the rights of our people come first, not the state of Mauritius. We are proud to be British citizens and we believe a true democratic future lies with the UK."
Speaking on the revelation that the Chagos Islands may have been used for torture, Vincatassin said: "Our homeland should only be used for good purposes, not as a second Guantanamo Bay with no set of rules or laws like other countries."
Vincatassin said that the government "should disclose how much money it has received" from the sale of .io domain names and asked the government to provide "assurances that it will be used for the islands, including the resettlement that so many Chagossians want to see happen."
