UK and France Abandon 'One In, One Out' Migrant Exchange Scheme as Channel Crossings Plummet

A flagship British-French arrangement designed to curb small-boat migration across the English Channel has been quietly wound down, the UK Home Office confirmed on Wednesday. The pilot programme, known informally as the "one in, one out" deal, had been intended to disrupt the business model of people-smuggling networks by returning undocumented migrants to France in exchange for an equal number of asylum seekers entering Britain through safe and legal routes.

The scheme was formally agreed in 2025 by then-prime minister Keir Starmer, who positioned it as a key element of a broader post-Brexit reset in relations between London and Paris. At the time, migration across the Channel had become one of the most contentious issues dividing the two neighbours, with successive British governments under pressure to demonstrate that they could control their borders while France faced criticism over the scale of departures from its northern coastline.

In a statement, the Home Office said the arrangement is "no longer processing new cases," effectively signalling its termination. The department nonetheless insisted that deportation flights will continue in the coming weeks for individuals who have already been detained under the scheme's provisions. This suggests that while the pipeline for new transfers has been shut off, the logistical machinery built up over the past year has not been entirely dismantled.

The mechanics of the deal were straightforward on paper. Migrants who reached British shores via unauthorised crossings could be detained and sent back to France, while an equivalent number of asylum seekers who had applied through official channels would be resettled in the UK. The programme initially set a target of 2,600 exchanges and was designed to run for three years, though it included a clause allowing either party to withdraw early.

According to Home Office data, the results fell well short of those ambitions. Between August 2025 and June 2026, approximately 1,117 asylum seekers travelled to the UK from France under the scheme, while 1,087 individuals were deported in the opposite direction. The near-parity in those figures reflects the reciprocal logic of the arrangement, but the overall numbers remained modest relative to the scale of irregular migration across the Channel.

UK Interior Minister Shabana Mahmood acknowledged in parliament this month that the programme had "not been without its challenges," adding that "the numbers are still relatively small." She pointed to operational difficulties in scaling up removals, noting that "what has been more operationally difficult is to scale up very large numbers of removals every week into the French system." Her remarks offered a rare public acknowledgement that the logistical demands of the scheme had outstripped the political will or administrative capacity to sustain it.

French newspaper Le Monde reported that while Starmer's successor, Andy Burnham, had pressed President Emmanuel Macron during talks in September to keep the arrangement alive, "Paris was in a hurry to end the cooperation on controlling migrant flows." The report suggests that French authorities had grown wary of the deal's operational burden and its implications for France's own asylum system, which was being asked to absorb returns at a pace it struggled to accommodate.

The apparent collapse of the scheme coincides with a dramatic decline in unauthorised Channel crossings, though officials attribute the drop to a range of factors rather than any single policy intervention. As of Sunday, some 19,135 people had crossed from France to Britain in 2026, representing a 42 percent decrease compared with the same period the previous year. The Home Office credited increased police patrols and enhanced surveillance along the northern French coast for contributing to the downward trend.

Despite that progress, the human cost of the crossings remains stark. On Monday, a ten-year-old child and two women died, apparently trampled in a boat packed with more than 100 people attempting the journey. At least 22 people have lost their lives in the Channel this year, according to an AFP tally drawn from official French and British sources, underscoring the persistent dangers faced by those seeking to reach British shores.

The perilous nature of the route was further emphasised on Wednesday when a French court sentenced six men to prison terms ranging from six to ten years for their roles in the deadliest Channel disaster on record. At least 31 people drowned in November 2021 when their vessel foundered off the French coast, an incident the court attributed to "individuals driven by greed, with utter disregard for human life."

The scrapping of the exchange programme leaves both countries without a structured bilateral mechanism for managing returns, at least for now. While the Home Office maintains that cooperation with France continues and that "real progress" has been made in tackling small-boat crossings, the end of the pilot raises questions about what, if anything, will replace it as a deterrent and a means of sharing responsibility for asylum seekers arriving in Western Europe.

For the UK government, the decision represents a pragmatic retreat from a policy that had come to symbolise the difficulties of translating political declarations into operational reality. For France, it removes a source of friction but also a channel through which returns could be managed in an orderly fashion. The broader challenge of preventing dangerous crossings — and of dismantling the smuggling networks that profit from them — remains unresolved on both sides of the water.
