UK-France ‘one in, one out’ asylum pilot stops taking new cases

The UK-France ‘one in, one out’ asylum pilot stopped processing new cases on 30 September, according to the Associated Press, ahead of its scheduled expiry on 1 October. The change ends an exchange under which Britain returned some people who crossed the Channel in small boats while admitting asylum seekers from France through a legal route. It leaves the two governments without that particular route for returns and admissions, while the effect of the pilot on crossings remains unproven.

How the UK-France asylum exchange worked

Under the arrangement, a person who reached Britain by small boat could be sent back to France. In exchange, an asylum seeker in France could be admitted to Britain through a legal route. The arrangement was intended to deter dangerous crossings, but the available evidence does not establish how much it changed decisions to travel. The pilot was due to expire on 1 October; Le Monde reported that France’s Interior Ministry had confirmed discussions with Britain about the terms of its end.

The figures describe a limited operation beside the scale of Channel arrivals. The Guardian estimated that about 1,500 people had been returned to France and a similar number admitted legally to Britain. It reported more than 40,000 small-boat arrivals during the period the arrangement was in place. Those figures indicate the size of the exchange, but they cannot show whether people who did not cross were deterred by it.

Other estimates cover different periods. The University of Oxford’s Migration Observatory calculated about 1,100 returns between September 2025 and June 2026, equivalent to 4% of small-boat arrivals during those months. Le Monde cited a parliamentary figure of about 1,400 returns. The Guardian’s estimate is about 1,500. These figures have different coverage and should not be read as competing final counts for the same period.

Why the pilot ended

France had raised a broader objection to bearing the returns alone. French Interior Minister Laurent Nuñez said at a parliamentary hearing that France should not carry the burden by itself and argued for an agreement between Britain and the European Union, according to the Guardian. The report said other European countries had not agreed to join the scheme. No replacement for the exchange is established in the available accounts.

The pilot also drew criticism over its treatment of people subject to removal. The Guardian reported, citing Home Office freedom-of-information data, that force was used against one in 10 of 224 asylum seekers during removals to France in the first three months of 2026. It reported concerns raised by Medical Justice and health organisations about physical and psychological harm. Home Secretary Shabana Mahmood suggested some injuries might have been self-inflicted; Labour MP Bell Ribeiro-Addy disputed that suggestion, citing independent evidence about the use of force.

What the crossing figures can show

Small-boat arrivals fell in 2026, but that decline cannot be assigned to the exchange alone. The Migration Observatory calculated about 27,900 arrivals in the year ending 9 September 2026, 40% below the September 2025 peak and 11% below the level when Labour took office in July 2024. It counted about 16,300 arrivals from the start of 2026 to 9 September, 47% fewer than in the same part of 2025.

The Observatory said policy changes might have played a part, but their effects cannot be separated reliably from other causes. It identified a fall in detected unauthorised crossings into the EU as one possible contributor: those crossings declined 26% in 2025 and a further 37% in the first half of 2026. Because many people who reach Britain by small boat travel through the EU first, fewer arrivals there could eventually mean fewer journeys toward the Channel. The Observatory did not assign a measured share of Britain’s decline to that factor or to the returns pilot.

What remains after the returns pilot

Britain and France have a separate agreement on preventing crossings. Announced by the Home Office in April 2026, it covers patrols, intelligence work and technology in northern France. The Home Office said it included £500 million for the control system and a further £161 million for actions whose funding would depend on evaluation. It set out a planned rise in funded personnel from 907 in the 2023–26 cycle to 1,392 in the 2026–29 cycle. Those are commitments and targets, not measured results from the future deployment.

Ending the returns exchange therefore does not end all UK-France cooperation on Channel crossings. It does, however, remove the pilot’s paired route for returns to France and legal admissions to Britain. The Home Office has said it will continue to remove as many small-boat arrivals as possible, according to the Guardian, but the reporting does not establish what arrangement, if any, will replace this specific exchange. The separate patrol agreement is subject to joint evaluation; its eventual effect on crossings is also unknown.
