France, Europe: Paris prepares to end the migration agreement with Britain as Channel crossings remain a persistent political and security concern
France is preparing to end its controversial migration agreement with the United Kingdom, despite repeated British efforts to preserve the arrangement designed to address irregular Channel crossings and establish a new framework for asylum cooperation.
The pilot agreement, commonly called “one in, one out” in Britain and “un pour un” in France, was signed in July 2025 and was scheduled to expire on October 1, according to information confirmed by the French Interior Ministry.
British authorities had pushed strongly for an extension of the arrangement, viewing the agreement as an important element of efforts to discourage migrants from making dangerous journeys across the English Channel in small boats toward Britain.
The new Labour prime minister, Andy Burnham, reportedly raised the issue during an early September meeting with French President Emmanuel Macron in London, seeking continued cooperation as pressure over irregular migration remained a significant political issue.
Paris, however, has been increasingly reluctant to continue the pilot. French authorities have indicated that discussions are now focused on how the agreement will be brought to an end rather than whether it should be extended.
“We are discussing with the British the terms of exiting the agreement,” France’s Interior Ministry told Le Monde, confirming that negotiations between the two countries were centered on ending the arrangement.
The agreement represented a significant change in French policy because it established a mechanism under which Britain could return certain migrants to France after they had crossed the Channel by small boat.
In exchange, Britain agreed to admit an asylum seeker from France through a legal route, creating a reciprocal system intended to connect enforcement against irregular arrivals with expanded opportunities for lawful asylum migration.
The arrangement was unusual because France had previously resisted British requests to accept migrants returned after reaching British territory through irregular routes, despite years of diplomatic pressure surrounding the Channel migration crisis.
The policy shift followed the appointment of Bruno Retailleau as French interior minister in September 2024. His arrival coincided with stronger French and British efforts to develop measures aimed at reducing irregular crossings.
British officials argued that the prospect of being returned to France could discourage migrants from attempting the dangerous Channel journey, particularly if they believed reaching British territory would no longer guarantee that they could remain there.
The Channel route has remained a persistent challenge for successive British governments, with migrants continuing to attempt crossings in small boats despite increased cooperation between French and British authorities.
The journeys are frequently undertaken in overcrowded and unsuitable vessels, creating serious risks for people attempting to cross one of Europe’s busiest waterways. The issue has consequently become closely linked to border enforcement and asylum policy.
For Britain, the agreement offered a mechanism for demonstrating that irregular arrivals could result in removal while simultaneously providing selected asylum seekers with a legal route into the country.
For France, however, the arrangement required cooperation with a policy that could place additional responsibility on French authorities for people returned from Britain after attempting to cross the Channel.
The disagreement illustrates the broader difficulties faced by European governments seeking to manage irregular migration while maintaining legal asylum pathways and bilateral relationships with neighbouring countries.
The French decision also comes as Britain continues to seek stronger international cooperation to address small-boat crossings, which have remained politically sensitive despite various measures introduced to strengthen border controls.
The end of the pilot does not necessarily mean that France and Britain will stop cooperating on migration. Both countries remain closely connected geographically and politically, and officials are expected to continue discussions over border security and irregular movement.
However, ending the one-in, one-out arrangement removes a specific mechanism that was intended to combine returns with legal admission. Its conclusion therefore represents a setback for Britain’s attempt to establish a reciprocal migration framework with France.
The agreement had also carried symbolic importance because it marked the first time France accepted the principle of receiving migrants returned from Britain after irregularly entering the country through the Channel route.
Its termination could therefore influence future negotiations between London and Paris, particularly if British officials seek another arrangement designed to increase returns or strengthen the deterrent effect of border enforcement.
At the same time, France faces its own pressures surrounding migration management, including the need to process asylum applications, manage irregular arrivals and coordinate migration policies with European partners.
The disagreement highlights the competing priorities of the two governments. Britain has emphasized reducing irregular arrivals, while France has sought to manage cooperation without permanently accepting responsibilities that could expand because of Britain’s Channel migration policies.
The future of bilateral migration cooperation will depend partly on whether the two governments can develop another framework acceptable to both sides. Any replacement could involve different rules governing returns, legal migration routes and responsibility for asylum seekers.
For now, the French Interior Ministry’s confirmation indicates that the existing pilot is approaching its conclusion. The precise terms of the withdrawal are expected to be discussed between French and British officials.
The decision comes at a sensitive moment for both governments, as migration remains a major public policy issue across Europe. The experience of the pilot is likely to shape future discussions over how Britain and France manage the Channel.
With the agreement ending, London will face the task of developing alternative arrangements to address irregular arrivals, while Paris will need to determine how far it is prepared to cooperate with British efforts to control migration.
The outcome could become an important test of future Franco-British cooperation, particularly as both countries attempt to balance border enforcement, humanitarian obligations and legal migration pathways amid continued pressure along the Channel.
