UK–France 'One In, One Out' Migrant Deal Ends After Pilot Scheme Fails to Expand

The UK government's 'one in, one out' migrant returns arrangement with France has come to an end, following confirmation by the Home Office on 30 September 2026 that new cases would no longer be processed under the pilot.

The arrangement allowed some people arriving in Britain by small boat to be returned to France, with an equivalent number of eligible people transferred legally from France to the United Kingdom.

The agreement was intended to reduce incentives for dangerous journeys and disrupt people-smuggling networks.

How did the arrangement work?

The pilot began operating in August 2025.

Under the agreement, eligible small-boat arrivals could be detained and returned to France.

In exchange, other individuals could enter Britain through an authorised route, subject to identity, documentation, security and eligibility checks.

Official Home Office figures show that by 30 June 2026:

• 1,087 people had been returned from Britain to France.
• 1,117 people had been transferred from France to Britain.

By the end of September, media reports citing the Home Office indicated that approximately 1,500 people had been returned during the pilot.

Why has the agreement ended?

The government had sought to expand the pilot, but it did not reach the scale originally hoped for.

Reporting from news organisations indicated that French authorities favoured a broader arrangement involving the European Union rather than continuing the bilateral pilot.

The Home Office confirmed that the scheme was no longer processing new cases.

However, the department said returns involving people already detained under the arrangement could continue during the following weeks.

Does this mean UK–France border cooperation has stopped?

No.

The ending of the returns pilot is separate from the wider operational cooperation between British and French authorities.

Under a different agreement announced in April 2026, both countries committed additional police and surveillance resources to preventing small-boat crossings.

In August, the Home Office reported that French police had prevented 185 attempted small-boat crossing events between 27 April and 2 August.

That included interventions involving boats, equipment and suspected smugglers.

What happens next?

The end of the returns pilot raises questions about what arrangements could replace it.

These include whether a broader European returns framework could be negotiated, how the UK will manage people arriving without permission, and whether additional enforcement activity will reduce crossings.

The distinction between border prevention operations and post-arrival returns will be important when assessing future government claims.
