UK Scraps 'One In, One Out' Channel Migrant Returns Deal With France

The British government has confirmed that its pilot agreement with France to return some small boat arrivals while accepting an equal number of legal migrants from French territory has been discontinued. The arrangement, which became operational just over a year ago, will no longer process new cases, although removal flights are expected to continue in the coming weeks.

Under the scheme, the UK was permitted to send back a portion of those arriving on small boats across the English Channel, provided it simultaneously admitted the same number of individuals from France who were judged to have a legitimate claim to enter Britain. The reciprocal structure was intended to serve as a deterrent while maintaining a commitment to legal pathways.

Since its launch, approximately 1,500 people have been removed to France. The BBC understands that while the government would have preferred to keep the scheme running, ministers ultimately concluded it had not achieved the scale originally envisioned. The relatively modest numbers involved suggest that operational constraints prevented the pilot from becoming the broad returns mechanism that officials had hoped for.

A Home Office spokesperson said the "lessons learned" from the pilot would be applied to "accelerate efforts" to remove small boat migrants with no right to remain in the UK. The spokesperson confirmed that the pilot is no longer processing new cases, but stressed that flights would continue over the coming weeks to swiftly remove individuals who lack permission to stay. The government also maintained that it would keep working with France on tackling small boat crossings, pointing to what it described as "real progress," with arrival numbers significantly lower than the previous year.

The French Interior Ministry confirmed that discussions with the British side about the terms of exiting the agreement are ongoing. The phrasing indicates that both governments are still negotiating the practical details of winding down the arrangement, including any outstanding returns or administrative obligations.

The decision comes after Home Secretary Shabana Mahmood acknowledged earlier this month that the scheme had "not been without its challenges." She told MPs that the numbers involved remained "relatively small," and that scaling up very large weekly removals into the French system had proven operationally difficult. Her comments reflected long-standing concerns about the capacity of both countries to process and accept returns at a pace that would meaningfully affect overall arrival figures.

Mahmood also noted, however, that the United Nations and other agencies had reported that some migrants were not boarding small boats because they believed there was a chance of being accepted under the "one in, one out" framework. That observation is significant because it suggests the scheme may have had a deterrent effect beyond its direct returns, even if the government felt the overall scale fell short of expectations.

The pilot's costs have also attracted scrutiny. Mahmood previously stated that the scheme cost £56,000 per person returned to France, a figure that critics cited as evidence of poor value for money. Supporters argued that the expense had to be weighed against the broader deterrent effect and the alternative costs of accommodating asylum seekers in the UK.

Statistics illustrate the wider context in which the pilot operated. Between 1 January and 27 September 2026, a total of 19,135 people crossed the English Channel by small boat from France, a decline of 42% compared with the same period the previous year, when 32,188 crossed. Crossing numbers have followed a volatile trajectory since 2018, when just 299 arrivals were recorded. They rose sharply to 8,462 in 2020 and peaked at 45,755 in 2022, before falling to 29,437 in 2023 and climbing again to 36,816 in 2024.

Small boat arrivals have become the most common method by which people are detected entering the UK illegally since 2020. Nearly all of those who arrive by this route claim asylum, and under international law they are permitted to remain in the country while their applications are assessed. Small boat arrivals accounted for 40% of asylum applications between July 2025 and June 2026.

The boats themselves have grown more crowded. Vessels arriving between 28 September 2025 and 27 September 2026 carried an average of 67 people, more than double the figure recorded in 2021. Experts say overcrowding makes crossings considerably riskier, and at least 84 people died attempting to cross the Channel in 2024, according to United Nations figures. For scale, small boat arrivals represent roughly 5% of total immigration into the UK between January and December 2025.

The nationalities of those arriving reveal distinct patterns. People from Eritrea made up 18% of all arrivals between July 2025 and June 2026. The top five countries of origin were Eritrea, with 5,875 arrivals detected, followed by Sudan at 4,191, Afghanistan at 4,042, Somalia at 3,901 and Iran at 3,657. In addition, at least 2,335 people who arrived by small boat between January and December 2025 were identified as potential victims of human trafficking or other forms of modern slavery, according to Home Office figures.

Beyond small boats, 4,712 people were detected entering the UK without permission through other routes between July 2025 and June 2026, including hiding in vehicles, travelling on ferries or arriving through airports. That represented a 17% decrease on the same period a year earlier. There are also individuals who arrive legally on work or study visas and subsequently overstay, though the total number of people living in the UK illegally after legal entry is not known.

The government has pledged to "smash the gangs" responsible for organising crossings as part of its strategy to reduce arrivals. The scrapping of the pilot raises questions about what will replace it, particularly given the government's stated intention to accelerate removals of those with no right to remain. Whether the "lessons learned" translate into a more effective returns framework, and whether cooperation with France can be deepened without the reciprocal structure of the pilot, will be central tests of the policy in the months ahead.
