BRITAIN-EU-FRANCE-POLITICS-MIGRANTS

Britain has this year faced an unprecedented number of arrivals from migrants using small boats to cross the Channel. The situation has become a political headache for Britain, which vowed to "take back control " of its borders after leaving the European Union -- and strained ties with France.
