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.

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.

Sir Keir Starmer clashed with Tory leader Kemi Badenoch over the deal to hand over the Chagos Islands to Mauritius.
