The UK government has implemented a new bilateral agreement with France known as the 'one in, one out' migrant returns deal, aimed at reducing illegal crossings of the English Channel by small boats. The treaty, ratified in early August 2025, allows the UK to detain migrants arriving via small boats and return them to France, while France agrees to accept asylum seekers who have not attempted illegal entry into the UK. The UK Home Secretary, Yvette Cooper, confirmed that detentions under this scheme began within days of the treaty's enforcement, with the first migrants being detained and facing deportation back to France. The UK government has allocated an additional £100 million to support this initiative, including funding for the pilot scheme and enhanced police powers to seize digital devices related to people smuggling. The arrangement is part of Prime Minister Keir Starmer's broader strategy to curb irregular immigration. While the government has not specified an overall quota for returns under the deal, officials expressed optimism that the pilot scheme will contribute to reducing Channel crossings. The first detentions have been publicly confirmed by multiple sources, marking a new phase in UK-France cooperation on migration control. Separately, the UK has also conducted arrests targeting migrants working illegally in delivery services amid ongoing efforts to manage immigration. Protests have occurred outside asylum seeker hotels in London, with police presence outnumbering demonstrators. Additionally, from October 12, new European border rules will require UK travelers to provide proof of accommodation and return tickets for trips to the EU as part of a digital verification scheme.
