To ask the Secretary of State for the Home Department with reference to the amendment to Article 40 of the Schengen Agreement implemented by Article 1(i) of EU Council Decision 2003/725/JHA, on how many occasions the UK has conducted cross-border surveillance in another EU member state since 2003; and on how many occasions another EU member state has been authorised to carry out such surveillance in the UK.
The Serious Organised Crime Agency has collected data on requests for authority to continue surveillance into foreign jurisdictions under article 40 of the Schengen convention since 2008. In that time the UK has made 154 such requests and received five requests from other member states.
The figures do not represent the number of occasions that UK law enforcement actually conducted surveillance on foreign soil because such requests for continued surveillance are often facilitated by the receiving country, eliminating the need for UK law enforcement to travel. Of the five requests the UK has received from other member states, all were conducted by UK authorities rather than the requesting member state.
