(LONDON) The UK’s first migrant deportation flights to France under the new UK–France “one in, one out” returns deal are scheduled to begin the week of September 15, 2025, in what officials describe as a major change in cross-Channel enforcement. Up to four removals on regular Air France services are expected between Monday and Friday. Each flight will depart from London Heathrow Terminal 4, carry around 10 migrants, and include at least one security escort per person. The Home Office plans an initial pace of about 50 deportees per week, with numbers rising if the pilot runs smoothly.
Under the treaty, which took effect on August 5, 2025, the UK can return adults who arrived by small boat to France. In exchange, France will send an equal number of asylum seekers—people already approved by French authorities and typically with family or strong ties in the UK—to arrive here. The first reciprocal arrivals are expected on Saturday, September 20. Ministers say the approach is designed to stop dangerous journeys across the Channel and hit the smuggling business model that profits from them.

Home Secretary Shabana Mahmood said she expects first returns “imminently,” adding that protecting the border remains her priority and that she will explore all options to “restore order” to the immigration system. A Home Office spokesperson repeated that the treaty allows detention and removal to France for those crossing by small boat. Legal observers note the quiet rollout—small numbers, commercial flights, and close case screening—appears intended to reduce disruption and limit last-minute legal challenges.
How the removals will work this week
People selected for removal have been detained at Harmondsworth immigration removal centre since their arrival in August. Each has received a formal removal direction notice giving five days to seek legal advice or file a challenge.
On removal day:
- Secure vans will transfer detainees to Heathrow Terminal 4.
- They will board regular Air France flights, sitting alongside ordinary passengers.
- French authorities will receive the returnees on arrival and process them under French law, including any asylum or support claims available under national and EU rules.
Key procedural points:
- The returns deal applies only to adults. Children arriving illegally are not detained or removed under this arrangement.
- Officials in London and Paris say returns will scale up if early operations go to plan and procedures meet legal and safety standards.
- According to analysis by VisaVerge.com, both governments will review the agreement after the pilot phase, with the option to widen scope if operational results are strong.
The initial flights reflect a cautious approach:
- Expected to carry as few as 10 migrants each.
- Every person escorted by trained staff.
- The low-key rollout aims to avoid protests and last-minute injunctions, and to manage capacity (trained escorts, booked seats, checked case files).
Government sources say departures and weekly totals will increase once the system is operationally stable.
Policy context and political stakes
More than 31,000 people have crossed the Channel in small boats so far in 2025—the highest number at this point in the year. The government argues the returns deal with France is necessary to reduce crossings, alongside wider work with European partners to target smugglers.
Prime Minister Sir Keir Starmer has placed the policy at the center of his pledge to bring order to the border after the previous government’s Rwanda plan was shelved in 2024. Ministers also point to a steep drop in hotel use for asylum accommodation—from more than 400 hotels in 2023 to fewer than 210 in 2025—as evidence that pressure on the system is easing.
This method marks a departure from traditional charter flights (commonly used for foreign national offenders or removals to countries of origin). The focus here is:
- Prompt returns to France (the country many small boat arrivals departed from).
- Reciprocal admissions of people who qualify in France but have ties to the UK.
Officials characterize the structure as fair and balanced, stressing its reciprocal nature: every person returned to France is matched by one approved asylum seeker admitted to the UK.
Legal, rights, and welfare concerns
Rights groups and legal advisers are watching closely. Key concerns include:
- Access to lawyers during the five-day window.
- Risk of errors in case screening.
- What happens to people after landing in France (reception, support, vulnerabilities).
NGOs will monitor detention conditions, escorts’ conduct, and whether vulnerabilities—such as medical issues or exploitation risks—are taken into account. Government lawyers state each removal will follow established rules, with access to legal remedies.
For individuals facing removal:
- A removal direction notice starts the five-day countdown.
- Within that time they can:
- Seek legal counsel.
- Apply for judicial review.
- File other legal challenges.
- The Home Office says it will pause removal if a court orders it, or if new evidence changes the person’s legal position.
- If removal proceeds, French authorities will register and process the returnee under French asylum and immigration procedures, which may include reception centers, case interviews, and support programs in line with French and EU standards.
Operational details: flights, escorts, and airline considerations
The flights will use standard Air France passenger services—a choice that reduces visibility and cost but raises practical questions for airlines and fellow passengers.
- Airline staff will work with Home Office contractors escorting each person.
- Training covers de-escalation and safety to ensure journeys proceed without incident.
- Early operations will include extra buffers for boarding times and security handovers.
Government data tracking:
- The Home Office plans to track weekly removals, legal outcomes, and reciprocal arrivals.
- The public will want evidence on whether crossings fall, smuggling networks feel pressure, and the returns process holds up in court.

France’s operational role
Officials in Paris must receive, screen, and support people returned from the UK while coordinating with prefectures and asylum authorities. Important factors:
- Reception capacity and local services will shape how smoothly returns are absorbed.
- Coordination includes sharing passenger manifests, escort details, and medical information.
- Protocols exist for unexpected events, such as legal stays or medical diversions.
Expected impact and criticisms
The new approach changes the messaging for people on the move: smugglers selling a UK destination may find some arrivals returned to France within days. If the message spreads and removals are steady, officials believe fewer people will risk the crossing.
Points of debate:
- Critics question whether returns at ~50 a week can meaningfully dent crossings.
- Ministers argue numbers will grow if the pilot is reliable, citing early police cooperation and the low-profile use of commercial flights.
- Supporters say the package restores control and reduces Channel harm.
- Opponents warn that without faster asylum decisions and more legal routes, people will continue to take risks and removals will address only a fraction of arrivals.
For families and communities in the UK, reciprocal entries matter: people with close family or strong UK ties recognized by French authorities will enter lawfully under the one-for-one principle. Officials stress this is not a broad resettlement program but a targeted channel that may reduce pressure on dangerous routes.
Advice and legal preparation
Legal practitioners advise anyone given a removal notice to:
- Seek legal advice immediately.
- Use the five-day window to prepare challenges.
- Gather supporting documents (medical reports, trauma evidence, proof of family links, etc.).
Case outcomes may hinge on vulnerabilities, health issues, family links, or new evidence.
How success will be measured
The Home Office will measure success by three operational metrics:
- Steady removals with minimal disruption.
- Reciprocal admissions that run on time.
- Favourable legal outcomes when cases are challenged.
The French government will monitor:
- Reception capacity.
- Processing times.
- Whether returnees access entitled support under French law.
Both sides have committed to a formal review after the pilot, with adjustments based on early evidence.
What to watch this week
If flights depart on schedule, escorts operate quietly, courts handle urgent filings, and arrivals in France are processed smoothly, officials will claim early proof the model works. If flights face injunctions or operational snags, ministers could face pressure to rethink pace and scale.
For now, the government is betting a careful, rules-based start will build the foundation for larger numbers in the weeks ahead.
This Article in a Nutshell
The UK plans to start limited deportation flights to France the week of September 15, 2025, under the UK–France returns treaty effective August 5. Up to four Air France services will carry around 10 adult migrants each, escorted by trained staff, with the Home Office targeting about 50 removals weekly during the pilot. The arrangement is reciprocal: France will admit an equal number of asylum seekers approved there who have UK ties. Detainees receive a removal direction notice and five days to seek legal advice or challenge removals. Officials emphasize careful screening, legal safeguards, and a cautious rollout to limit disruption and potential injunctions while both governments review operational results before scaling up.
