UK Ends 'One In, One Out' Channel Returns Pilot With France
The UK government has scrapped its 'one in, one out' agreement with France for returning Channel small-boat arrivals. The Home Office said the pilot will take no new cases, but removal flights will continue over the coming weeks.
How the scheme worked
Under the scheme, the UK could return some small-boat arrivals to France and admit the same number of people from France assessed as having a legitimate claim to come to Britain, according to the BBC. Intake has now stopped, but cases already in the system, known as the pipeline, have not yet closed.
Around 1,500 people have been removed to France since the scheme began just over a year ago. The Home Office has linked the decision to end the deal to that low number of returns, as reported by the Telegraph. The figure is small against total arrivals.
Why it has stopped
Inside Whitehall, the scheme ran as Operation Hillmore. Inspectors described it as a pilot set up for one year. The government announced the first detentions under the UK-France deal in August 2025, according to GOV.UK. That year has now passed.
Paris has not described this as a sudden break. The French Interior Ministry told the BBC it is discussing the terms of exit with Britain. Outstanding cases and removal flights still have to be handled.
So far this year 19,135 people have made the Channel crossing. That is 42% lower than the same period in 2025, when 32,188 people crossed in small boats.
What happens now
The broader context here is that a reciprocal pilot of this kind depends on speed and volume. It needs detention space, swift decisions, seats on flights or other removal routes, French agreement on each return, and a matching admissions stream running at the same pace. If one part slows, numbers stay low and political pressure builds.
For the Home Office, the practical point is clear. Intake is closed but enforcement is not. Flights in the coming weeks will clear cases already in the system while officials negotiate the formal exit. The questions for ministers and select committees (the cross-party groups of MPs who check policy) will be practical: how many cases remain, what happens to people detained under the pilot who cannot now be removed under it, and what, if anything, replaces it.
Looking at the crossing figures, the 42% year-on-year fall gives ministers room to argue the wider Channel strategy is having an effect. It does not by itself show whether the pilot helped bring about the fall, or whether deterrence, weather, enforcement in northern France or other operational factors mattered more. That will need a fuller Home Office account of returns and outcomes.
