The United Kingdom has halted its “one in, one out” arrangement with France, a pilot programme that allowed the return of some small‑boat arrivals in exchange for admitting an equivalent number of French nationals with legitimate claims to reside in Britain. Officials say the scheme, which has seen roughly 1,500 people returned to France since its launch just over a year ago, did not achieve the scale the government had hoped for. While the Home Office stresses that lessons from the pilot will be used to speed up removals of those without right to remain, it also confirms that flights will continue in the coming weeks to swiftly return small‑boat migrants. Both London and Paris pledged to keep working together to deter Channel crossings, noting that numbers have fallen markedly compared with the previous year.
Background of the “one in, one out” pilot
The agreement, introduced as a trial, was designed to create a balanced flow: for every migrant sent back to France, the UK would accept one person from France who had a strong legal basis to come to Britain. The idea was to deter risky boat journeys while offering a lawful route for those genuinely seeking protection. A Home Office spokesperson explained that the pilot is no longer processing new cases, adding that “lessons learned” would be used to “accelerate efforts” to return small boat migrants with no right to remain. The spokesperson also said that flights would continue over the coming weeks to swiftly remove such individuals, and that the insights gained would help accelerate those efforts.
Official figures show that, since the scheme began, only around 1,500 people have been removed to France. The government had hoped to expand the programme but concluded it had not reached the desired scale. Home Secretary Shabana Mahmood told MPs that the numbers were still relatively small and that scaling up weekly removals into the French system had proved operationally difficult. She also noted that UN and other agencies had reported some migrants refraining from boarding boats because they believed they might be accepted under the reciprocal arrangement.
Impact and statistics on Channel crossings
Despite the scheme’s termination, the broader picture of Channel crossings shows a significant decline. Between 1 January and 27 September 2026, 19,135 people crossed the English Channel in small boats from France – a drop of 42 % compared with the same period in 2025, when 32,188 made the journey. These crossings remain the most common method by which people are detected entering the UK illegally since 2020, and nearly all of those who arrive claim asylum.
Small‑boat arrivals accounted for roughly 40 % of asylum applications between July 2025 and June 2026. The average boat carried 67 people during the period from 28 September 2025 to 27 September 2026, more than double the average seen in 2021. The United Nations recorded at least 84 deaths linked to Channel attempts in 2024. In terms of overall migration, the number of small‑boat entrants represents about 5 % of total immigration into the UK for the calendar year 2025.
The government has repeatedly pledged to “smash the gangs” behind these voyages. Data also reveal that Eritrean nationals made up 18 % of arrivals from July 2025 to June 2026, and that at least 2,335 people who came by small boat between January 2025 and December 2025 were identified as potential victims of human trafficking or modern slavery. Additionally, 4,712 individuals entered the UK without permission via other means – such as concealment in vehicles or on ferries – during the same July 2025‑June 2026 window, a figure down 17 % on the previous year.
Government response and future plans
While ending the reciprocal deal, ministers emphasise that cooperation with France will continue. The Home Office spokesperson affirmed that the UK would “continue working with France to tackle small boat crossings,” highlighting that “real progress” had been made with numbers “significantly down on last year.” The French Interior Ministry told the BBC that discussions were under way regarding the terms of exiting the agreement.
The Home Secretary also disclosed that the scheme cost approximately £56,000 for each person returned to France, a figure she shared in a statement dated 15 September. Officials say the money saved from ending the pilot will be redirected toward broader enforcement measures, including intelligence‑led operations against smuggling networks and faster processing of asylum claims for those who do arrive.
Plans to accelerate removals of individuals lacking legal status will draw on the operational insights gained from the pilot. The government insists that flights will remain active in the short term to ensure swift returns, while longer‑term strategies focus on deterrence through improved intelligence sharing and joint patrols with French authorities.
Humanitarian and operational considerations
Critics of the scheme have argued that its limited throughput did little to deter the underlying push factors driving people to undertake perilous crossings. Advocacy groups point out that many of those arriving are fleeing conflict, persecution or extreme poverty, and that the prospect of a legal return route may have offered a false sense of security to some. The UN’s warning about the risks of overcrowded boats underscores the human cost of the journey, with fatalities remaining a stark reminder of the need for safer pathways.
On the operational side, officials acknowledged the difficulty of scaling up weekly removals to match the volume of arrivals. Coordinating with French reception centres, arranging escorts and ensuring compliance with international legal obligations proved more complex than anticipated. The decision to end the pilot reflects a recognition that, without a substantially larger capacity to process returns, the scheme could not meet its original objectives.
Why it Matters
The termination of the UK‑France “one in, one out” deal signals a shift in how Britain intends to manage irregular Channel crossings, moving from a reciprocal exchange model to a strategy centred on accelerated removals and stronger enforcement cooperation. With crossing numbers already falling, the government’s focus on dismantling smuggling gangs and using lessons from the pilot could shape future immigration policy, influencing both the flow of asylum seekers and the broader debate over Britain’s approach to humanitarian obligations and border security. The outcome will be watched closely by European partners, human rights organisations and the public, as it may set a precedent for how wealthier states balance deterrence with protection in an era of heightened migration pressures.
