Sir Keir Starmer has come under fire at PMQs after Mauritius said the UK had agreed to change payment terms in its deal to hand it control of the Chagos Islands. It comes after Mauritian PM Navin Ramgoolam claimed the UK had now agreed to front-load the payments and change how they are calculated.

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.

Britain and Mauritius denied on Wednesday media reports that London could end up paying double the amount in a renegotiated deal to retain a U.S.-British military base on Diego Garcia in the Indian Ocean.

The Tory leader says Labour's negotiations could cost the UK billions; the prime minister questions whether Badenoch has been "properly briefed" on UK security.

A satellite communications system used by the US and UK to run military operations is central to efforts by Britain to resolve the sovereignty of the Chagos islands, UK security officials familiar with the matter said.

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.
