Sir Keir Starmer has been accused of surrendering Gibraltar after striking a deal that allows Spain to check passports on the Rock.

Britain agreed a deal with Europe and Madrid that would place Spanish border officers at the airport and ports of the British territory as part of a “dual” entry system.

Those arriving on the land border will be waved through by British officials to ease border friction as part of the last of the major post-Brexit agreements.

The deal also removes physical checks on goods at the frontier with Spain.
