A "one in, one out" deal agreed by the UK and French governments on Thursday proposes that for each migrant the UK returns, Britain will accept another who has made a legal claim in France.

The UK and France have agreed to a ‘one in, one out’ migrant deal that will see failed asylum seekers returned to France for the first time since Brexit.

Britain will grant asylum to one migrant in France who can prove a family connection to the U.K. in exchange for each arriving migrant taken back by France.
