If Britain wants to remain a reliable partner in our security alliance, it must be willing to defend its sovereignty. As much as President Trump uses unpredictability as a diplomatic tool, I can predict one thing for sure: there is no way he will allow Britain to give up its sovereignty over the Chagos Islands.

A British minister denied on Wednesday media reports that the government could end up paying billions of pounds more to Mauritius under a renegotiated deal to retain a U.S.-British military base on Diego Garcia in the Indian Ocean.

Britain's government insisted Thursday that it must hand back the Chagos Islands to Mauritius to secure continued access to satellite communications at a key US-UK military base.
