Covert policing in the United Kingdom
Most British police forces have formed a unit solely for covert policing operations. One of the forces that makes extensive use of surveillance-led policing is Greater London's Metropolitan Police. The Metropolitan Police unit was formerly a Specialist Operations designation devoted to covert policing, which was SO10. Since then, most of the Specialist Operations units have been disbanded or merged, giving way to SO10 being merged into the Specialist Crime Directorate to be designated SCD10. Now designated as SC&O 10, it falls under the purview of Specialist Crime & Operations.
