The Outer Islands of Mauritius is the first-level administrative divisions of the country and consists of the islands of Mauritius and several outlying islands. The Outer Islands of Mauritius are managed under the aegis of the Prime Minister of Mauritius through Prime Minister's Office by the Outer Islands Development Corporation which is the authority empowered under the law to manage the Outer Islands of Mauritius. The Prime Minister is also Minister for Rodrigues, Outer Islands and Territorial Integrity. The Constitution of Mauritius states that the Republic of Mauritius includes the islands of Agaléga, Mauritius, Rodrigues, Saint Brandon, Tromelin Island, and the Chagos Archipelago. The Chagos Archipelago are set to be returned to Mauritius in 2025, after a long dispute with the United Kingdom. Additionally, France shares a sovereignty claim over Tromelin Island, an uninhabited island between Madagascar and Mauritius's main island.
