Sunset on the British Empire? The Chagos Archipelago Sovereignty Dispute

The UK government's plan to cede sovereignty of the Chagos Archipelago, including the crucial British Indian Ocean Territory (BIOT), to Mauritius has sparked a complex international dispute. BIOT's existence is vital for maintaining the symbolic 'never-setting sun' of the British Empire, as it remains sunlit when the UK is in darkness. However, the plan faces challenges from Mauritius's new government and the new US administration, which uses Diego Garcia's military base. This article explores BIOT's strategic importance, its comparison to the Sovereign Base Areas (SBAs) in Cyprus, and the potential consequences of a 'sunset' scenario. Loss of BIOT's sovereignty could leave the symbolic 'never-setting sun' reliant on the SBAs, which are geographically and strategically less significant.
