Britain and France agreed Thursday to a pilot plan that will send some migrants who cross the English Channel on small boats back to France as the U.K. government struggles to tamp down criticism that it has lost control of the country’s borders.

Keir Starmer has announced a 'one-in, one-out' deal to send migrants back to France if they try to arrive on small boats. The deal will see one illegal migrant sent back in exchange for an asylum seeker who has not tried to cross the Channel illegally.
