High confidence: 7/11 signals corroborated across 9 distinct outlets

The UK government has reversed its commitment to transfer sovereignty of the Chagos Islands to Mauritius, following direct pressure and criticism from US President Donald Trump. This decision, confirmed by UK Defence Secretary Wes Streeting, includes the suspension of lease payments to Mauritius and signals a renegotiation or abandonment of the previous agreement. The future status of the Diego Garcia military base and UK-Mauritius relations are now uncertain.

Why it matters: This reversal impacts strategic US-UK military presence in the Indian Ocean, decolonization efforts, and UK foreign policy alignment with the US.
