"They have got a wide range of experience to call upon for different jurisdictions and different problems."

Different jurisdictional interests may arise between prosecuting authorities and regulators, both domestically and overseas, depending on the type of offence and the type of corporate and individual suspects. Many agencies, including the police, Serious Fraud Office (SFO), Financial Conduct Authority (FCA), Crown Prosecution Service (CPS), Health and Safety Executive (HSE) and others may be interested in the same set of facts.

Prosecutors should be mindful of the protocols set out in The Prosecutors Convention and establish communication with any other relevant agency at an early stage to ensure effective liaison and co-operation.

In respect of overseas investigations and prosecutions both Eurojust and the Judicial Assistance Network have to date played a crucial role in the coordination and facilitation of prosecutions. Following the UK's withdrawal from the EU, a new co-operation model with Eurojust in being put in place. There is also the Guidance for Handling Criminal Cases with Concurrent Jurisdiction Between the United Kingdom and the United States of America.
