Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment her Department has made of the potential effect of the outcome of the EU referendum on the Government's ability to tackle terrorism.

Cooperation with our European partners has not ceased since the result of the referendum was announced. UK authorities continue to cooperate with their counterparts in other EU Member States bilaterally, including by using the Schengen Information System (SIS II), Europol, Eurojust, the European Arrest Warrant and other measures.

These tools, developed under the EU’s legislative framework, enable practical cooperation and information sharing, which is of value. However, much of our cooperation on counter-terrorism and national security matters sits outside of EU structures, including the Five Eyes, the closest international intelligence-sharing arrangement in the world, and the Counter Terrorism Group (CTG), a cooperation forum between the security services of EU Member States plus Norway and Switzerland, which sits outside EU law.
