A deal between Britain and France allowing the UK to return some migrants who cross the English Channel came into force on Tuesday. It's the latest step towards dismantling the criminal trade in small boat crossings and preventing dangerous journeys at sea.
The agreement, which was struck between Prime Minister Keir Starmer and President Emmanuel Macron during the latter's state visit to the UK last month, involves a "one-in, one-out" scheme to curb record levels of irregular Channel crossings.
