The police, the judiciary and public prosecutors cooperate in many ways at EU level. The EU agency Europol supports member states’ police forces in their efforts to fight serious crime, particularly by enhancing the exchange of information. The European Border and Coast Guard Agency (Frontex) is continuously being provided with more staff in order to better protect the external borders. Eurojust improves cooperation between member states’ judicial authorities with a view to prosecuting serious cross‑border crime. It does so, for example, by enabling the formation of joint investigation teams (JITs). The recent establishment of the European Public Prosecutor’s Office (EPPO) further strengthens judicial cooperation. The EPPO is responsible for investigating and prosecuting crimes against the financial interests of the EU, for example in connection with subsidies.
