Our police forces of course co-operate with other police forces throughout the world in bringing criminals and perpetrators to justice. The European arrest warrant—I will repeat myself—is an extradition arrangement that improves on the extradition arrangements that we had previously. I recognise that there have been concerns about it, but we have legislated on those concerns here in this Parliament.
I was describing the Prüm system, which is about the easy, efficient and effective comparison of data when appropriate. We have been clear that we cannot rejoin that on 1 December and would not seek to do so. However, in order for the House to consider the matter carefully, the Government will produce a business and implementation case and run a small-scale pilot with all the necessary safeguards in place. We will publish that by way of a Command Paper and bring the issue back to Parliament so that it can be debated in an informed way. We are working towards doing so by the end of next year. However, the decision on whether to rejoin Prüm would be one for Parliament. Unlike the Labour Government, who signed us up to that measure in the first place without any idea how much it would cost or how it would be implemented, the Government will ensure that Parliament has the full facts to inform its decision.
On another subject, I know that my right hon. Friend the Justice Secretary will want to address the probation situation in his closing remarks—that is another measure we have successfully resisted rejoining.
The Government propose to rejoin other measures in the national interest. We wish to rejoin the European supervision order, which allows British subjects to be bailed back to the UK rather than spending months abroad awaiting trial. That will stand alongside the reforms we have made to the European arrest warrant,
and make it easier for people such as Mr Symeou to be bailed back to the UK and prevent such injustices from occurring in future.
We are also seeking to rejoin the prisoner transfer framework decision, a measure that my right hon. Friend the Justice Secretary considers important. The framework helps us to remove foreign criminals from British jails—prisoners such as Ainars Zvirgzds, a Latvian national convicted of controlling prostitution, assault, and firearms and drug offences. In April 2012, he was sentenced to 13 and a half years imprisonment in the UK. Last month, he was transferred out of this country to a prison in Latvia, where he will serve the remainder of his sentence. Had it not been for the prison transfer measure, he would have remained in a British prison, at a cost to the British taxpayer of more than £100,000.
We wish to rejoin the measure providing for joint investigation teams, so that we can continue to participate in cross-border operations such as Operation Birkhill. That collaboration with Hungary, funded by Eurojust and assisted by Europol, led to five criminals being sentenced at Croydon Crown court last month to a total of 36 years imprisonment for their involvement in trafficking more than 120 women into the United Kingdom from Hungary, the Czech Republic and Poland. One of those convicted, Vishal Chaudhary, lived in a luxury Canary Wharf penthouse and drove a flashy sports car bought from the money he made selling those women for sex. Chaudhary and his gang managed their operation from a semi-detached house on a suburban street in Hendon, and operated more than 40 brothels across London, including in Enfield and Brent. Their victims were threatened with abuse if they tried to contact their families. Some were forced to have sex with up to 20 clients a day. These are the victims of crime that the measures we are debating to day help. Joint investigation teams are a vital tool in the fight against modern slavery, a crime this House so passionately demonstrated earlier this week it wants to see tackled. I hope the House will support rejoining the measures that will help us to do that.
