Nigel Farage Reveals What He Will Do With Foreign Criminals Serving Time in UK Jails
Nigel Farage has revealed one of the most hard-line elements of Reform UK’s law-and-order agenda, promising sweeping action against foreign nationals serving prison sentences in Britain.
The proposal comes as pressure on the UK’s overcrowded prison system reaches a critical point. Reform argues that thousands of foreign criminals are occupying prison places that could otherwise be used for British offenders, while taxpayers continue to pay the cost of keeping them behind bars.
Farage’s answer is blunt.
He wants foreign criminals removed from the British prison system and, where legally and practically possible, deported to their countries of origin. Where that is not possible, Reform is now exploring the possibility of sending some offenders to third countries to serve their sentences.
The proposal has immediately generated controversy.
Reform says the policy is about protecting the public, reducing pressure on prisons and ensuring that criminals serve their sentences without Britain carrying the full cost of imprisonment.
Critics, however, warn that the plan could face major legal, diplomatic and logistical obstacles.
The most striking part of Farage’s latest proposal is the possibility of using third-country prisons.
Reform has specifically pointed to countries such as El Salvador and Kosovo as potential destinations. The party has also indicated that MPs will travel to El Salvador to examine whether its prison system could accommodate foreign national offenders.
That represents a dramatic escalation of Reform’s previous position.
The party is no longer talking simply about deporting foreign criminals after they have completed their sentences.
It is discussing the possibility of removing them from British prisons altogether.
The argument behind the policy is straightforward.
Britain has a prison-space crisis.
If a foreign national has been convicted of a serious crime and is serving a prison sentence in Britain, Reform argues that there is little reason for British taxpayers to continue paying for that incarceration if the prisoner can legally be transferred elsewhere.
The party has reportedly identified around 10,000 foreign nationals currently held in British prisons as the group it wants to target.
Farage’s supporters see an obvious opportunity.
Free prison places.
Reduce costs.
Deport convicted foreign criminals.
And send a message that Britain will no longer provide what Reform describes as an unnecessarily expensive prison service for offenders who have no right to remain in the country.
But there is an important distinction between political ambition and practical implementation.
A foreign criminal cannot simply be placed on a plane and sent to another country without the necessary legal authority and cooperation.
The UK must have somewhere to send them.
The receiving country must agree.
There may need to be diplomatic arrangements governing prisoner transfers.
And British courts may be asked to consider challenges involving human rights, detention conditions and the legality of removing individual prisoners.
These issues could make Farage’s promise considerably more difficult to implement than it sounds from a political platform.
Britain already has mechanisms for deporting foreign criminals.
The Government has expanded its removal and detention capacity, and official figures say that nearly 70,000 people with no right to remain in the UK have been removed since the current government took office, including around 10,000 foreign national offenders.
Existing law also provides for automatic deportation in certain circumstances.
The Sentencing Act 2026, for example, strengthened provisions concerning foreign criminals sentenced to at least 12 months, including by bringing suspended sentences into relevant calculations.
So Reform’s argument is not that Britain has no deportation powers.
Its argument is that those powers are not being used aggressively enough.
Farage has previously supported proposals that would lower the threshold for automatic deportation. A Reform amendment to the Sentencing Act proposed an immediate deportation order for foreign criminals receiving a custodial or community sentence of at least six months, subject to exceptional cases. Parliament had not decided that amendment.
The latest proposal goes further still.
It seeks to connect immigration policy directly to the prison crisis.
That is politically powerful because Britain’s prisons are under severe pressure.
Ministers are currently examining ways to create additional capacity, including upgrading some Category C and women’s prisons. The prison estate is already struggling with overcrowding, while courts face significant backlogs.
Reform argues that there is a simple question that governments have failed to answer.
Why should Britain build more prisons for foreign criminals when some of those prisoners could instead be removed from the country?
That question will resonate with voters who believe Britain’s criminal justice system has become too lenient.
Farage has also promised a broader prison-building programme.
Reform wants to create thousands of additional temporary prison places, reportedly using a model inspired by the Nightingale hospitals built during the Covid pandemic. The party says these facilities could be constructed relatively quickly and would allow prisoners to serve longer portions of their sentences.
This is important because Farage’s policy is not simply about deportation.
It is part of a much larger philosophy.
Reform argues that prison sentences should mean what they say.
If a court imposes a sentence, the criminal should expect to spend a substantial proportion of that period behind bars.
The party wants to reduce reliance on early release and increase prison capacity so that governments are not forced to release offenders early because there are simply not enough cells.
Foreign criminals, in this model, become a special category.
If they have no right to remain in Britain, Reform argues that deportation should be prioritised.
The political appeal is obvious.
It combines two issues that voters already care deeply about: immigration and crime.
Instead of discussing them as separate problems, Farage presents them as one.
A foreign national convicted of a serious offence is not merely an immigration case, he argues; they are also consuming scarce prison capacity.
That framing allows Reform to claim that deportation could simultaneously strengthen Britain’s borders, reduce prison overcrowding and save taxpayers money.
But critics will ask whether those savings are as straightforward as Reform suggests.
Sending prisoners abroad could itself be expensive.
The UK might have to negotiate financial arrangements with receiving countries.
There would be monitoring and legal costs.
There could also be challenges over prison standards and treatment.
The proposal involving El Salvador is particularly controversial because the country’s prison system has attracted international attention for its extremely harsh approach to criminal detention.
A British government would therefore face difficult questions about whether it could transfer prisoners to a system operating under standards acceptable under British law and international obligations.
That is where the political battle could become fierce.
Farage will argue that criminals should not be allowed to exploit legal protections to avoid deportation.
Opponents will argue that Britain cannot simply outsource imprisonment to whichever foreign government is willing to accept the money.
Both sides will claim to be defending the public.
The ultimate test, however, will be whether the policy can actually work.
There is also the question of countries refusing to cooperate.
What happens if a foreign government refuses to accept its citizen?
What happens if the prisoner’s nationality is disputed?
What happens when a prisoner faces persecution or serious mistreatment in the proposed destination?
What happens if British courts block a deportation?
These are not theoretical questions.
They are precisely the kinds of problems that have historically complicated deportation policies.
The government already has a framework for dealing with foreign nationals in British prisons. Official guidance covers everything from notifying embassies and referring prisoners to the Home Office to immigration detention and deportation procedures.
Reform’s proposal would therefore require a major expansion of existing policy rather than simply signing a few agreements.
Yet politically, Farage may have little incentive to make the policy sound simple.
His political strength comes partly from presenting complicated problems in clear language.
For his supporters, the message is straightforward:
If you commit serious crimes in Britain and you are not a British citizen, you should not expect Britain to provide you with a permanent prison home.
That is a powerful slogan.
But governing is harder than campaigning.
If Farage ever becomes Prime Minister, he would have to turn that slogan into contracts, legislation, international agreements and court-defensible procedures.
That is when the real test would begin.
The foreign-prisoner plan nevertheless tells us something important about Reform’s political direction.
The party is attempting to transform itself from a protest movement into a potential governing party.
It is no longer simply demanding that Britain “do something” about immigration.
It is presenting detailed — and highly controversial — proposals for how the state should act.
The question is whether voters will see these plans as decisive leadership or reckless experimentation.
For some, there will be no ambiguity.
They will see Farage’s proposal as long-overdue common sense.
For others, the prospect of sending prisoners to countries such as El Salvador will appear deeply troubling.
And for the Government, there is an uncomfortable political problem.
Some of the issues Reform is exploiting are genuine.
Britain really does have a prison-capacity crisis.
Foreign criminals really are being held in British prisons.
Deportations really are taking place.
And the Government is already investing heavily in immigration enforcement.
The argument is therefore not about whether the problem exists.
It is about how far Britain should go to solve it.
Farage has made clear where he stands.
He wants foreign criminals removed from Britain’s prisons and, where possible, removed from Britain itself.
If countries of origin will not cooperate, Reform is prepared to explore third-country arrangements.
And if the prison system remains overcrowded, he wants new capacity built so that serious criminals are not released simply because there is nowhere to put them.
It is an uncompromising vision.
Whether it is also a workable one remains to be seen.
The coming months will show whether Reform can turn its proposals into credible international agreements and legally robust policy.
But one thing is already clear.
Nigel Farage is making foreign criminals and Britain’s prison crisis a central part of his political pitch.
His message to voters is simple: Britain should not be forced to choose between deporting foreign criminals and finding room for them in overcrowded prisons.
He wants to do both.
The political consequences could be enormous.
If the policy succeeds, Farage will claim it proves that a tougher approach to crime and immigration is possible.
If it collapses under legal, diplomatic or financial pressure, his opponents will argue that the proposal was always more about headlines than government.
For now, however, Farage has put the issue firmly on the political agenda.
And Britain’s overcrowded prisons may have just become the next major battlefield in the country’s immigration debate.
