The United Kingdom and France have formalised a new agreement aimed at reducing illegal Channel crossings through coordinated enforcement and prevention measures. The partnership reflects continued bilateral cooperation on border security and migration control, building on previous efforts that have already prevented tens of thousands of attempted crossings.
The agreement was announced on 23 April 2026 during a visit by UK Home Secretary Shabana Mahmood to Dunkirk, France, where she signed the deal alongside French Interior Minister Laurent Nunez. The three-year arrangement expands joint operations in northern France, where most small boat departures originate, with increased funding, personnel deployment and technological surveillance.
Under the terms of the agreement, £662 million will be invested over the 2026 to 2029 cycle to strengthen control systems along the northern French coastline. This includes £500 million for core border security enhancements and an additional £162 million allocated for flexible interventions subject to annual joint evaluation based on effectiveness in reducing crossing attempts.
The funding represents an increase from previous cycles and supports a 53% expansion in personnel deployment, rising from 907 agents in the 2023–2026 period to 1,392 in the new 2026–2029 cycle. These personnel include police officers, intelligence services and maritime prefecture staff, with the addition of a dedicated Compagnies Républicaines de Sécurité (CRS) unit managed by France to tackle illegal immigration.
Enhanced surveillance and technology deployment
As part of the security upgrades, France will deploy millions of pounds worth of drones, two helicopters and advanced camera systems to intercept people smugglers and detect small boat departures along the coast. These tools are intended to improve surveillance capabilities and enable faster response to potential launch points used by migrant vessels.
The agreement also includes provisions for infrastructure investments in Dunkirk and Calais, including the completion of a removal centre first announced in 2023. Once operational, the 140-capacity facility will be staffed by over 200 officers and focus on processing migrants from nationalities identified as the top origins of Channel crossings, including Eritrea, Afghanistan, Iran, Sudan, Somalia, Ethiopia, Iraq, Syria, Vietnam and Yemen.
UK officials have stated that the centre aims to facilitate the removal of hundreds of migrants per year from French beaches, either through deportation to their countries of origin or transfer to other EU nations they have transited through. The Home Office has not confirmed specific performance targets that France must meet to retain the flexible portion of UK funding, noting that continued financial support will depend on joint evaluations of impact.
Intelligence-led operations and smuggling disruption
Joint intelligence efforts will be expanded under the agreement to disrupt organised smuggling networks operating across the Channel. Previous cooperation between UK and French authorities has already yielded results, with joint actions leading to the arrest of 480 smugglers in 2025 and preventing more than 42,000 illegal crossings since the 2024 UK general election.
Home Secretary Shabana Mahmood described the deal as a “landmark agreement” that would “really arm us to go after the people smugglers,” emphasizing the require to target organised crime groups profiting from vulnerable migrants. French Interior Minister Laurent Nunez echoed this sentiment, stating the agreement gives French security forces “the means to continue their decisive commitment in the fight against dangerous Channel crossings.”
The partnership maintains flexibility for future adjustments, with UK funding including a variable component that can be redirected or withdrawn after one year if agreed-upon benchmarks for reducing departures are not met. This performance-linked approach marks a shift from previous fixed-funding models and introduces greater accountability into the bilateral arrangement.
Broader European coordination
Both governments affirm that the Channel agreement forms part of wider European cooperation on border security, treating the maritime route as an external EU border within operational coordination frameworks. The UK and France aim to strengthen collaboration with European partners, including the European Border and Coast Guard Agency (Frontex), to enhance information sharing and joint patrol effectiveness.
Efforts will also extend beyond immediate enforcement to address root causes of migration, with both countries pledging to perform with countries of origin and transit to disrupt migrant flows before they reach northern France. This upstream approach complements coastal interdiction by targeting smuggling infrastructure and recruitment networks in source regions.
The agreement comes amid ongoing political pressure in the UK to demonstrate tangible progress on reducing small boat arrivals, which have remained a persistent challenge despite previous deterrent measures. While crossings have fluctuated year-on-year, the latest data shows continued attempts, underscoring the need for sustained international cooperation.
Officials from both nations stress that the agreement is not a standalone solution but one component of a broader strategy combining enforcement, intelligence, return agreements and development cooperation. Future reviews will assess whether the expanded resources and flexible funding model achieve the desired reduction in illegal crossings over the three-year term.
