British authorities continue to participate in many EU instruments in the area of justice and home affairs, and cooperation in some cases even goes further than with the Schengen states Norway, Iceland or Switzerland. The exit from Europol and the Schengen Information System could strengthen the secret services.
With its withdrawal from the European Union, the UK will have left the „European Area of Freedom, Security and Justice“ as of 1 January 2021, and the country will become a third country from the EU’s perspective. This will also end cooperation within the framework of the Schengen Agreement. The government in London will lose its place as one of the most important partners in the EU security architecture. The loss of participation in the Schengen Information System (SIS II) will probably weigh heavily in the UK. In 2019, British police forces and intelligence services had around 37,000 persons and 4.5 million objects stored there. Many covert Article 36 alerts, which allow police and domestic intelligence to track the movements of wanted persons across the EU, also originated in the UK.
However, British authorities are to be allowed to continue to participate in important EU information systems in the area of Justice and Home Affairs (JHA) and also to cooperate with agencies. These are the provisions of the provisional „EU-UK Trade and Cooperation Agreement“ (TCA), which the parties negotiated at the last minute before the turn of the year. „Privileged third country: EU security cooperation with Great Britain after Brexit“ weiterlesen
