Law enforcement in the United Kingdom is organised separately in each of the legal systems of the United Kingdom: England and Wales, Northern Ireland and Scotland. Most law enforcement is carried out by police officers serving in regional police services within one of those jurisdictions. These regional services are complemented by UK-wide agencies, such as the National Crime Agency and the national specialist units of certain territorial police forces, such as the Specialist Operations directorate of the Metropolitan Police.
