The United Kingdom and France have agreed to overhaul the 'one-in, one-out' treaty that governs the processing of migrants crossing the English Channel, with a new provision designed to stop individuals removed from British territory from re-entering France. The revised accord, announced by Home Office officials on Tuesday, aims to close a loophole that had allowed some deported migrants to quickly return to French coastal areas and attempt further crossings.
Key Changes to the Treaty
Under the original 2023 agreement, for every migrant removed from the UK, France agreed to accept a corresponding number of migrants from British processing centres. However, critics noted that many of those removed were later found back in northern France, attempting to cross again. The new text explicitly states that individuals removed under the treaty will be barred from re-entering French territory for a period of at least five years, with biometric data shared between the two countries to enforce the ban.
According to a joint statement from the UK Home Secretary and the French Interior Minister, the revised treaty also includes increased funding for joint patrols and surveillance technology along the French coast. 'This strengthened partnership ensures that those who are removed cannot simply turn around and try again,' the statement read.
Impact on Channel Crossings
The number of small boat arrivals in the UK has fallen by 25% in the first half of 2026 compared to the same period last year, with 8,500 migrants making the journey. However, the government has faced pressure to reduce the figures further. The new measures are expected to deter repeat attempts, which accounted for an estimated 15% of all crossings in 2025.
Home Office data shows that of the 1,200 migrants removed to France under the original treaty in 2025, at least 180 were later identified as having made a second crossing attempt. 'This is a significant step in breaking the cycle of returns and reattempts,' said a Home Office spokesperson.
Reactions and Criticism
While the treaty revision has been welcomed by some Conservative MPs, refugee advocacy groups have condemned it as a breach of international obligations. 'Denying people the right to seek asylum is not a solution,' said Sarah Jones of Refugee Action. 'The focus should be on safe routes, not on pushing people back.'
The French government has also faced domestic criticism for agreeing to the ban, with some lawmakers arguing it undermines France's sovereignty over its borders. Nonetheless, both governments have emphasised the need for joint action to manage migration flows.
