LONDON: Britain said it will begin implementing a deal to return some migrants who arrive on small boats to France within days, a key part of its plans to cut illegal migration, after a treaty on the arrangement is ratified on Tuesday. Under the new deal, France has agreed to accept the return of undocumented people arriving in Britain by small boats, in exchange for Britain agreeing to accept an equal number of legitimate asylum seekers with British family connections.

The "one-in, one-out" deal will see some of those arriving in the UK returned to France.

Some asylum seekers will be sent back across Channel for first time under treaty agreed with French president
