Reality Check: How many UK citizens are extradited?
The question: Alan asks BBC Radio 4' s PM programme: "How many UK citizens have been arrested and extradited to other EU states compared with citizens of other EU states extradited to the UK?"
Reality Check verdict: In the financial years 2009-16, 7,436 people were extradited from the UK to another EU country. Of these, 292 were UK nationals. Meanwhile, 897 people were extradited to the UK. Of these, 352 were EU nationals.
If someone is wanted by an EU country in relation to a crime, and that country suspects the individual might be living in another member state, they can make a request for arrest under the European Arrest Warrant.
If the suspect is identified, they can then be arrested by a local police force.
In the financial years 2009-16, 10,532 people wanted by another EU state were arrested in the UK.
Of these, 479 were UK nationals, although more may have been permanent UK residents.
After the appeals process, 7,436 people were actually extradited from the UK to another EU country to stand trial or serve their prison sentence.
Of these, 292 were UK nationals.
In the same time period, 10% of that figure, or 1,054 people, wanted by the UK were arrested on its behalf by another EU state.
Of these, 444 were EU nationals.
The rest were either British citizens or from another part of the world.
Of these, 897 people were extradited to the UK.
And of these, 352 were EU nationals - but more may have been permanent EU residents.
