Britain’s year-old pilot to return some Channel small-boat arrivals to France in exchange for an equal number of legal migrant places has ended without renewal, the Home Office confirmed on Wednesday, leaving ministers to lean on other enforcement tools as crossings remain a flashpoint in UK–EU relations.

The so-called “one in, one out” arrangement, launched under the previous government as part of a broader Brexit reset, was due to lapse on Thursday. French Interior Minister Laurent Nunez had told London in June that the pilot was never meant to continue beyond 1 October 2026, and the French ministry said this week it was in talks to withdraw formally.

What London says stopped

A Home Office statement said the pilot “is no longer processing new cases,” adding that the government would have “willingly” kept it running. A UK government source told reporters the scheme “did not reach our desired scale,” echoing comments Home Secretary Shabana Mahmood made to Parliament this month that operational challenges had limited weekly removals into the French system.

Le Monde reported that Prime Minister Andy Burnham pressed President Emmanuel Macron during September meetings to preserve the exchange, but that Paris was eager to end cooperation on returns even as both capitals face domestic pressure over Channel deaths and smuggling networks. Legal challenges on both sides of the Channel had slowed individual cases, further shrinking the pilot’s numbers.

Political stakes in Westminster

For Burnham’s administration, the collapse of the pilot removes a tangible symbol of post-Brexit pragmatism with France just as the government promotes wider EU security and trade outreach. Conservative and Reform-aligned MPs are likely to argue the failure proves bilateral deals cannot substitute for deterrence, while refugee charities warn that ending structured returns without expanding safe routes could push more people into irregular crossings.

Mahmood has paired enforcement rhetoric with expanded returns flights to third countries where agreements exist, but officials acknowledge those routes move far fewer people than the tens of thousands who have crossed the Channel in recent years.

What happens next

Civil servants said cases already in the pipeline would be handled under existing immigration rules, but no new matched pairs would enter the exchange. Downing Street did not announce a replacement framework on Wednesday, and French officials gave no indication they would reopen negotiations before France’s 2027 presidential cycle hardens migration politics further.

Charities including the Refugee Council had warned that ending the pilot without expanding family reunion or humanitarian visas would leave fewer regulated paths open even as smugglers advertise faster irregular routes on social media.

Border Force and National Crime Agency teams will continue joint patrols and intelligence sharing that sit outside the pilot, diplomats said. For now, the practical effect is a return to pre-pilot processing on both shores—without the headline promise that each removal would unlock a controlled legal arrival for someone already waiting to come to Britain.

Numbers ministers would not publish

Home Office officials told MPs in July they would release paired-case statistics each quarter, but no full tally appeared before the pilot lapsed. Charities and the Home Affairs Select Committee chair both said the absence of data made it impossible to test whether legal arrivals actually offset removals, or whether legal challenges in French administrative courts throttled throughput.

Immigration lawyers on both coasts said many matched cases stalled on age disputes and family-unit definitions, shrinking the weekly pipeline Mahmood described in Parliament. Without transparent figures, Downing Street could claim diplomatic progress even as operational returns stayed in the low hundreds.

Local authorities brace for impact

Kent County Council leaders said hotels used for temporary accommodation remain near capacity, and the end of matched returns removes a talking point they used when lobbying for Home Office funding. French prefectures along the coast reported similar pressure on asylum housing, illustrating why both governments needed a workable legal route rather than a symbolic pilot.

Smugglers’ marketing on encrypted apps barely mentioned the pilot, according to National Crime Agency briefings seen by reporters, suggesting deterrence never reached the criminal supply chain regardless of diplomatic headlines.
