A very expensive policy
Fifty six thousand pounds. That is the cost. It is the price the government is paying to persuade France to take back a single person who has crossed the Channel. The figure is not a leak, nor an opposition estimate spun for effect, but a formal admission from the home secretary herself. The policy is known inside the Home Office as the 'one in, one out' deal, a bilateral arrangement that was supposed to represent a breakthrough in managing illegal migration. Instead, the price tag attached to each individual return transforms it into something else entirely. It becomes a symbol of expensive failure. A very big number for a very small result.
The sum came to light on Tuesday. It fell from the home secretary's lips. Shabana Mahmood was giving evidence to the Home Affairs Select Committee, a regular and often tedious part of her job. MPs on the committee had been pressing her on the new French agreement, specifically on whether it was delivering value for the taxpayer. The questions were predictable. The answer was not. Mahmood told the room that the cost for every person sent back across the water was running at approximately £56,000. The admission hung in the air of the committee room, a stark confirmation of a policy that is struggling badly. This was not a proud announcement. It was a forced confession under parliamentary scrutiny.
The problem is one of simple arithmetic. The costs are high because the numbers are low. Mahmood conceded that the figures for people actually returned under the scheme remain ‘relatively small’, a piece of Whitehall understatement for what is clearly a tiny trickle of individuals. Grand policies announced at press conferences are meant to operate at scale, yet this one appears to be functioning as a boutique, artisanal service with a price to match. A flagship returns policy that barely returns anyone creates a brutal calculation, one where the huge financial and political capital invested is divided by a laughably small number of successful cases. The result is a per person cost that looks, to most people, completely indefensible. The entire project is crippled by its own mathematics.
The view from the Home Office
The view from the Home Office is rehearsed. It is also predictable. Shabana Mahmood came to the committee armed with a defence, one designed to blunt the impact of her own admission. The home secretary’s primary argument is one of operational friction. She explained to MPs that the policy has proven ‘difficult’ to scale up. This is Whitehall code. It means the system is not working smoothly yet. New bilateral schemes, her department would argue, always have teething problems, bureaucratic hurdles to clear and logistical chains to build from scratch. The implicit message is one of patience. Costs are high because volume is low, but volume will increase as the machinery of removal becomes more practised. This is the core argument. Give us time.
Then came the counterattack. It was a simple pivot. Mahmood argued that the £56,000 figure, while large in isolation, is not the whole story. She offered a direct comparison. The home secretary stated that the cost was roughly the same as, or potentially less than, accommodating a single person in a hotel for a full year. This is the government’s key talking point. It is a political shield. The argument attempts to transform a number that looks like an expensive failure into one that looks like a prudent investment in future savings. The debate is no longer about the cost of removal. It is about the much greater cost of inaction.
This reframing is a calculated political strategy. It is not an apology. The Home Office is not expressing regret for the high price tag, it is justifying it by pointing to a different, more politically damaging expense. Every successful return, according to this logic, prevents a year of costly hotel bills which voters despise. The £56,000 is presented not as money lost, but as a liability avoided. It is an argument designed to resonate on the government’s own backbenches, where anxiety over asylum accommodation costs has been growing for years. This logic will now be repeated. Ministers will use it all week. They will hope it cuts through.
The home secretary’s defence, therefore, rests on two pillars. One is a plea for patience, the other is a bold redefinition of value for money. She conceded the numbers returned are ‘relatively small’. She had no choice. But she immediately contextualised this weakness as a temporary phase in a difficult but necessary process. The government’s position is that the scheme is a work in progress, an essential tool that is still being calibrated. The price is high, but the price of the alternative, they insist, is higher still. The department asks for perspective.
How the deal is supposed to work
The policy has a simple name. 'One in, one out'. The name implies a straightforward, almost automatic exchange, a neat piece of political accounting where one person leaves as another arrives. This is not the reality. The system is not a conveyor belt moving people from Dover to Calais, it is a complex and highly individualised negotiation that takes place for every single person the UK seeks to send back to France. It is not a unilateral British action. It is a bilateral deal. This is the crucial point. Britain cannot act alone.
Because the arrangement is bilateral, it requires constant agreement. The process is not automated. For every individual the Home Office identifies for removal, officials must compile a case and formally request that their French counterparts accept that person. Paris must then give its consent. Explicitly. Without that specific French approval for that specific person, the return cannot happen. Nobody moves. This grants the French government a person by person veto over the entire scheme, a power it can exercise for any reason, political or administrative, with no need for a public explanation. It is an immense amount of leverage. Absolute leverage.
This French veto is the primary reason the policy is so slow and so costly. It creates an enormous bureaucratic bottleneck by its very nature. Every proposed return generates a cascade of paperwork, legal assessments, and official communication between ministries in London and Paris. The procedure is deliberately slow. It is designed that way. Each case file is a potential point of diplomatic friction, requiring careful management to avoid a wider political argument between the two governments. The process is less a logistical operation and more a series of painstaking micro negotiations, each one carrying the risk of failure and delay. A civil servant in a Kent processing centre cannot simply approve a transfer. The decision is made in Paris.
This is how the £56,000 bill is built. The price reflects the immense staff hours, legal resources, and diplomatic effort required to secure French agreement on a case by case basis. The UK is effectively paying for the privilege of asking permission. The structure of the deal gives France control over the flow of people and, consequently, over the operating costs of the entire programme. Paris sets the tempo. It can choose to speed things up, or slow them to a crawl, depending on its own domestic political needs or its objectives in other areas of the UK, France relationship. The British government is not the sole actor here. It is a junior partner in its own flagship policy.
Labour's political price
Fifty six thousand pounds. It is a politically lethal figure. The opposition does not need to explain the complexities of bilateral agreements or asylum processing backlogs, they just need to repeat the number. It is an amount that cuts through any official explanation. Labour now has a single, powerful figure to hammer the government with at every opportunity, from Prime Minister’s Questions to local election leaflets. The government looks incompetent. It looks wasteful. The cost for returning a single person is so high that it creates an immediate political scandal, one that requires no spin or detailed policy knowledge to be understood by voters. It is a gift.
This was a flagship policy. It was meant to demonstrate control. Now it demonstrates the opposite. It shows a government held captive by costs and by Paris. The prime minister made this a personal pledge. The failure is therefore personal. For Shabana Mahmood, the situation is acute. She is the home secretary who had to reveal the number under questioning at the Home Affairs Select Committee on Tuesday. Her defence, that the cost is comparable to housing a migrant in a hotel for a year, does little to change the headline figure which is now fixed in the public mind. It is her number now. It will follow her. Her argument that the scheme has been ‘difficult’ to scale up sounds less like a sober assessment and more like an admission of failure from a minister who has lost control of her own department’s central policy.
The political headache is huge. This is not just about one policy. It poisons the government's entire message on immigration and public spending. The opposition can frame every debate around that one figure. Every time a minister talks about tackling illegal migration, the shadow minister will simply say ‘£56,000’. The sum is so large and the result so small that it makes the government's competence on any major project questionable. This is the real price. It is not about the money. It is about authority lost. That is much harder to recover. The prime minister now faces a serious problem of his own making, tied to a policy that produces excruciating headlines and almost no tangible results. The pressure from his own backbenches to either fix the scheme or scrap it will become immense. They will want answers.
Paris calls the tune
This arrangement has two partners. Only one has power. The ‘one in, one out’ policy is not a simple administrative process which can be scaled up with more staff or a bigger budget. It is a series of individual diplomatic requests, with each person proposed for return requiring the specific consent of the French authorities before they can be put on a boat or a plane. That gives Paris a veto. A veto on every case. The French interior ministry can approve, delay or deny returns for any reason at all, whether for sound administrative purposes or for purely political calculations made in the Élysée Palace. The entire system is built on French discretion. London can only ask.
What is the French incentive to say yes? This is the question nobody in the Home Office seems able to answer convincingly. For a French president, there is almost no domestic political advantage in being seen to accept large numbers of people back from the United Kingdom, particularly when those people have already left French territory. The current arrangement is perfect for Paris. It allows the French government to appear cooperative to an international partner while controlling the flow to a trickle, ensuring the numbers never become a problem for French regional authorities or a target for Marine Le Pen. It exports a problem. Why would they want it back?
This leverage does not exist in isolation. It is a powerful tool. The British desperation to make the returns scheme work, a desperation advertised by the prime minister’s own pledges, gives Paris an advantage that extends far beyond the English Channel. Every negotiation, on any topic from fishing quotas in the Bay of Biscay to defence procurement, now takes place with this imbalance in the background. Does London need French support for a new security initiative, or a concession on financial services regulations, or a quiet word in Brussels? The French can be helpful. Or they can be difficult. The pace of migrant returns provides a useful, real time barometer of cooperation, a diplomatic thermostat that can be adjusted at will without ever having to be mentioned in a formal meeting. London pays the £56,000. Paris sets the real price.
What to watch for now
The government is now trapped. It has two choices. It can abandon the policy or it can double down. Neither option looks good from inside Number 10. The path of least resistance, and the one most familiar to struggling administrations, is to insist that everything is going to plan. Expect to see Shabana Mahmood sent out to broadcast studios to repeat her argument. The home secretary will claim the scheme is in its infancy, that it is difficult, and that the costs will fall dramatically once it is operating at scale. This is a huge political bet. The entire defence rests on the unproven assumption that the number of returns will rise sharply in the coming months, which is a decision that rests almost entirely with officials in Paris, not in London.
The alternative is a quiet, managed retreat. No minister will ever announce the scheme has been scrapped. That would be an admission of failure too public to bear. Instead, the 'one in, one out' branding would simply vanish from speeches and press releases, replaced by a new set of buzzwords and a focus on different, hopefully more successful, policies. The money would be reallocated. The weekly operational meetings would be cancelled. The policy would die not with a public execution but from administrative neglect, a common fate for failed Whitehall projects that have become too embarrassing to mention but too politically sensitive to kill off formally. It simply ceases to be.
Three things will reveal which course the prime minister has chosen. The first is ministerial language. Watch for the next big interview given by the home secretary or the prime minister on the topic of immigration. If they defend the programme by name and promise future results, they are doubling down. If they pivot to talking about a 'broader package of measures', the retreat has already begun. The second is the next set of Home Office quarterly migration statistics. Figures are not opinions. If those numbers show another period with only a handful of returns, the government’s argument that costs will fall with scale will become impossible to sustain. The numbers will kill the policy.
The final, and most important, signal will come from across the Channel. The scheme lives or dies by French consent. A statement from the French interior ministry offering to accelerate the process would be a lifeline for the British government. A pointed public silence from Paris would suggest it is perfectly happy with a slow, expensive arrangement that gives it maximum leverage over London for minimal effort. For now, Whitehall waits. Westminster waits. The next move belongs to France.
