The Blue Ensign reflects British administration of the Chagos Archipelago. The coat of arms and flag feature white and blue wavy lines for the Indian Ocean, a palm tree for the tropical atolls, the St. Edward's Crown for British sovereignty, and the Union Jack in the canton.
History
The flag was officially granted on November 8, 1990, for the British Indian Ocean Territory created in 1965. The archipelago's sovereignty is disputed, with Mauritius claiming the territory and the UN General Assembly calling for decolonization.
