UK-France Renew Historic Agreement on Illegal Channel Crossings Amid Humanitarian Concerns

The Sandhurst Treaty, a key agreement between the UK and France aimed at combating illegal crossings of the English Channel, has been renewed for three years with significant modifications. This renewal, announced on April 23, 2026, includes increased financial commitments and enhanced enforcement measures to curb dangerous attempts to enter the UK from France.

Under the new treaty, the UK has pledged a total of €580 million—an increase from the previous €540 million—with €186 million now partially conditional on the effectiveness of the measures implemented. The plan involves doubling the number of agents preventing illegal departures along the French coast by 2029, reaching approximately 1,400 personnel. A specialized French National Police (CRS) unit will also be deployed to focus on illegal immigration using drones, helicopters, and electronic surveillance to monitor and prevent clandestine crossings.

Despite these efforts, 2025 saw 41,472 irregular crossings reported, the second-highest since the treaty's inception in 2018. French authorities noted a 50% decrease from the prior year, but the issue remains critical. Furthermore, the treaty includes a "one-for-one" clause allowing the UK to return migrants who arrived illegally, exchanging them for migrants transferred from France. However, this mechanism has only affected a few hundred individuals so far.

Humanitarian groups, most notably Médecins Sans Frontières (MSF), have voiced serious concerns about the treaty's consequences. MSF highlights that these policies exacerbate precarious conditions for migrants trapped in France, leading to severe physical and psychological harm. Michaël Neuman, MSF’s Migration Program Manager in France, warned that restrictive enforcement forces migrants to undertake longer, perilous routes, including departures from more distant locations like the Belgian coast.

Liz Harding of MSF’s UK branch criticized the British government for spending over one billion pounds on deterrent measures that endanger lives rather than facilitating safe access and dignified living conditions. Since the last agreement in March 2023, more than 110 people have died attempting to cross the Channel. MSF argues that the "One in One out" policy, which leads to arrests and limited legal pathways, neither deters migration nor reduces fatalities but pushes migrants into the hands of traffickers and smugglers.

In summary, while the renewed treaty marks a reinforced bilateral effort to address illegal Channel crossings with increased funding and manpower, it also faces significant humanitarian critique over its impact on migrant safety and wellbeing. Officials from both countries now face the challenge of balancing border security with providing humane treatment and viable solutions to migration pressures.
