France and Britain are abandoning a landmark migration deal that allowed the British to return migrants who crossed the English Channel illegally in exchange for those who applied to enter via official means.
The deal, known as “one in, one out,” struck in the summer of 2025, was intended to deter dangerous illegal crossings of the channel, which have roiled politics in Britain and raised tensions between London and Paris. The original deal was struck for one year and was extended by a month, until Oct. 1, but will not be renewed.
