Keir Starmer was dramatically blocked from signing a deal to give away the Chagos Islands today.
The Prime Minister had hoped to announce the highly controversial handover of the Indian Ocean archipelago to Mauritius - a move branded a 'surrender' by critics.
Sir Keir was due to attend a virtual ceremony alongside representatives from the Mauritian government this morning to sign off on the deal.
It is expected to see Mauritius handed billions of pounds in rent for Diego Garcia, an island in the territory that is home to a major UK/US airbase.
But in the early hours of this morning it emerged a High Court has granted an injunction stopping the negotiations being concluded.
