UK-France Deal Aims to Curb Channel Crossings

A new three-year agreement between the United Kingdom and France, signed on March 27, 2025, in Dunkirk, France, aims to reduce undocumented migrant crossings of the English Channel. The deal renews and builds upon the Sandhurst Treaty, including increased funding, expanded law enforcement presence, and new interception tactics.

Funding and Conditions

Under the agreement, the UK will provide funding totaling up to €766 million ($897 million).

This comprises a base commitment of £500 million ($675 million) allocated to strengthening measures in northern France. An additional £160 million ($216 million) is contingent upon the success of new tactics; according to the UK Home Office, if these tactics fail to reduce crossings, the extra funding will be halted after one year. Nearly a quarter of the total funding is conditional on meeting specific effectiveness targets, according to UK government sources.

Operational Measures

The deal outlines a significant increase in law enforcement personnel. The number of officers deployed will rise from 907 to 1,392 for the 2026–2029 period, a 50% increase, according to the French Interior Ministry. This includes:

• A new 50-strong riot police unit dedicated to combating irregular migration
• Expanded intelligence and judicial teams
• Additional maritime patrols and a new vessel with extra maritime officers
• Enhanced surveillance capabilities, including drones, helicopters, and electronic monitoring

New technology will be deployed specifically to target "taxi boats"—small, motorized inflatable vessels used by smugglers to pick up migrants along the coast.

New On-Water Interception Policy

A key tactical change under the agreement is the authorization of on-water interceptions. French authorities conducted their first such operation on a Saturday in Gravelines on the Aa canal, where a suspected "taxi-boat" was boarded by officers. The inflatable dinghy, which reportedly carried several men believed to be people-smugglers, was towed to the dockside.

Previously, French police interventions were restricted to stopping boats as they were being prepared for launch on beaches, as intervening at sea was considered too dangerous. Smuggling gangs adapted by using "taxi-boats," which would enter the water some distance from shore and travel along the coast to pick up migrants already in the water. According to official French documents, this method had an 81% success rate in 2025.

The new on-water policy was first agreed upon at a summit in the UK in July 2025, involving President Emmanuel Macron and Prime Minister Keir Starmer. Its implementation was delayed due to concerns about risk to human life and potential officer liability. Under the revised terms, gendarmes will intervene to stop "taxi-boats" only before migrants have boarded the vessels. The procedure used in the Gravelines operation aligns with these terms, as police suspected the inflatable was preparing to pick up migrants.

Statistics and Context

The number of people crossing the English Channel in small boats has been a significant political issue in the UK.

• 2025 Annual Figures: Approximately 41,000 to 41,472 people crossed the Channel in 2025, the second-highest annual figure since records began in 2018, following a peak of 45,755 in 2022.
• 2026 Figures: As of early 2026, over 6,000 migrants have reached the UK via the Channel, a 36% drop compared to the same period in 2025. French officials report that arrivals in the UK have fallen by half since the start of 2026 compared to the same period in 2025. Both sets of figures may partly reflect weather conditions.
• Interdictions: The UK government stated that joint efforts have halted over 42,000 attempted crossings since July 2024.

Law Enforcement and Smuggler Arrests

French police operations led to the arrest of 480 smugglers in 2025, according to the French Interior Ministry. The agreement aims to increase these efforts.

Recent Incidents

Earlier in March 2025, two men and two women died while trying to board an inflatable boat off the northern French coast. British authorities arrested a man from Sudan on suspicion of endangering life in that case. The previous week, two other people died in similar circumstances off the coast north of Calais.

Migrant aid group Utopia 56 reported that at least 162 people have died at the French-UK border over the past three years.

Official Statements

UK Home Secretary Shabana Mahmood said the deal provides "the right mix of skills and capabilities that we know will work on the beaches in order to reduce the crossings."

French Interior Minister Laurent Nuñez said the agreement will help in "combating illegal immigration networks, human trafficking networks, which are obviously extremely harmful."

UK Prime Minister Keir Starmer stated that "our work with the French has already stopped tens of thousands of crossings and this government has deported or returned nearly 60,000 people with no right to be here."

Nicolas Laroye, representative of the police union UNSA in the Dunkirk region, said additional staffing will support police efforts to monitor over 200 kilometers of coast, adding that British-financed measures have had a major impact and drones have become a key tool.

Imran Hussain from the Refugee Council said, "Policing alone will not prevent desperate people from turning to dangerous small boats in the first place."
