Key Takeaways

  • The UK has extradition arrangements with all EU member states and several non-EU European countries.
  • Following Brexit, extradition between the UK and EU countries is primarily governed by the UK-EU Trade and Cooperation Agreement (TCA).
  • A person living in the UK can still be extradited to another European country for prosecution or to serve a sentence.
  • A person living elsewhere in Europe can also be extradited to the UK if UK authorities are seeking them.
  • Extradition is not automatic and UK courts carefully examine every request.
  • Human rights, unfair trial risks, nationality protections, and other legal defences may prevent extradition.

Summary

The UK maintains extradition agreements with all European Union member states and numerous non-EU European countries, including Norway, Switzerland, Iceland, Serbia, and Ukraine. If a European authority is seeking a person living in the UK, that person may face extradition proceedings before a UK court. Equally, if UK authorities are seeking someone who is living elsewhere in Europe, the UK can request that country's authorities to arrest and extradite them. However, extradition is subject to strict legal safeguards and judicial scrutiny.

Many people mistakenly believe that Brexit ended extradition arrangements between the United Kingdom and Europe. In reality, extradition continues to operate between the UK and most European countries through a combination of international treaties, the UK-EU Trade and Cooperation Agreement, and the Extradition Act 2003.

As international travel has become easier, criminal investigations increasingly cross national borders. A person accused of fraud in Germany may move to London. A suspect wanted by UK police may relocate to Spain. A convicted offender may leave France before serving a sentence.

When this happens, extradition law becomes critically important. Understanding which countries can request extradition and how the process works can help individuals understand their rights and the potential consequences of an international criminal investigation.

What Happens If Another European Country Is Looking for Someone Living in the UK?

If a European country believes a person in the UK has committed an extraditable offence, it can submit an extradition request through the appropriate legal channels. The individual may then be arrested and brought before a UK court to determine whether extradition should take place.

The process generally involves:

  1. 1 An extradition request is made by the European country.
  2. 2 The request is certified by the National Crime Agency.
  3. 3 The requested person is arrested.
  4. 4 Court hearings take place before Westminster Magistrates' Court.
  5. 5 The court considers any legal objections.
  6. 6 A final extradition decision is made.

If you have been arrested under a European extradition request, contact our police station solicitors immediately for urgent advice.

What Happens If UK Police Are Looking for Someone Living in Europe?

If UK authorities are seeking a suspect or convicted offender who is living in another European country, the UK can submit an extradition request to that country and ask local authorities to arrest the individual.

Depending on the country involved:

  • Local police may arrest the individual.
  • National courts will review the request.
  • Extradition hearings will take place.
  • The individual may challenge surrender.

If extradition is approved, the person will be returned to the UK to face proceedings or serve their sentence.

Can Someone Be Extradited for Any Crime?

No. Extradition is generally reserved for more serious offences. The offence must usually satisfy minimum seriousness thresholds and comply with the principle of dual criminality.

Offence Type Commonly Extraditable
Murder Yes
Serious Fraud Yes
Drug Trafficking Yes
Money Laundering Yes
Sexual Offences Yes
Terrorism Offences Yes
Minor Regulatory Offences Usually No

The seriousness of the offence remains an important consideration in every case.

What Is Dual Criminality?

Dual criminality means the alleged conduct must be criminal in both the requesting country and the requested country. If the conduct would not amount to a criminal offence in the requested country, extradition may be refused.

For example:

  • Fraud is criminal throughout Europe.
  • Drug trafficking is criminal throughout Europe.
  • Some politically related conduct may not satisfy the test.

Dual criminality protects individuals from being extradited for behaviour that is lawful where they are located. For detailed advice, speak to our criminal defence solicitors.

Can European Countries Refuse to Extradite Their Own Citizens?

Yes. Some European countries have constitutional protections that limit or prohibit the extradition of their own nationals to foreign countries.

Countries known for nationality restrictions include:

France
Germany
Poland
Finland

In some cases, these countries may choose to prosecute their own citizens domestically instead of extraditing them. This can significantly affect how a case proceeds.

Can UK Courts Refuse Extradition?

Yes. UK courts have a duty to refuse extradition where legal barriers apply. Extradition is never automatic simply because another country requests it.

Human Rights Concerns

  • Risk of torture
  • Inhuman prison conditions
  • Lack of fair trial rights
  • Serious medical concerns

Other Grounds for Refusal

  • Double Jeopardy: A person cannot usually be extradited if they have already been tried for the same offence.
  • Passage of Time: Extradition may be refused where excessive delay makes proceedings unfair.
  • Political Motivation: Requests motivated by political persecution may be rejected.

Our Crown Court advocates regularly raise these arguments in extradition appeals.

What Is an Interpol Red Notice?

An Interpol Red Notice is an international request to locate and provisionally arrest an individual pending extradition proceedings. It is not itself an arrest warrant, but it can lead to arrest in many countries.

Individuals often first discover they are wanted internationally after:

  • Being stopped at an airport
  • Applying for visas
  • Crossing borders
  • Being contacted by police

Early legal advice is essential if a Red Notice exists. Contact our magistrates' court defence team if you have been arrested following a Red Notice.

What Should You Do If You Think Another European Country Is Looking for You?

If you believe a European authority is investigating you, seeking your arrest, or pursuing extradition, you should seek specialist legal advice immediately.

A solicitor may be able to:

  • Verify whether a warrant exists.
  • Contact relevant authorities.
  • Challenge extradition requests.
  • Make bail applications.
  • Protect your legal rights.

Waiting until an arrest occurs often reduces available options. For comprehensive advice on the full extradition process, read our guide on criminal extradition in the UK.

Conclusion

The UK maintains extensive extradition arrangements with both EU and non-EU European countries. As a result, moving between European countries does not prevent criminal investigations, prosecutions, or prison sentences from being enforced.

If another European country is seeking someone who lives in the UK, that individual may face extradition proceedings before UK courts. Equally, if UK police are looking for a person who has moved elsewhere in Europe, the UK can request their arrest and return.

Because extradition law is highly specialised and the consequences can be severe, obtaining expert legal advice at the earliest opportunity is essential.
