The National Domestic Extremism Unit refers to specialist police organisation that began life as the National Coordinator for Domestic Extremism (NCDE) and was subsequently renamed the National Domestic Extremism Unit (NDEU) and more recently the National Domestic Extremism and Disorder Intelligence Unit (NDEDIU). For much of its history it was controlled by the Association of Chief Police Officers Terrorism and Allied Matters Committee, before being transferred to the the Metropolitan Police Service’s Counter Terrorism Command in the wake of the Mark Kennedy undercover scandal.
During its time under the control of ACPO, the NDEU consisted of a group of police units, several of which have gained national attention for their role in the policing of protests and deployment of undercover police into political and activist movements. These units were the National Public Order Intelligence Unit (NPOIU), National Extremism Tactical Coordination Unit (NETCU), National Domestic Extremism Team (NDET). Many began as separate units, or created out of the merger of smaller units around the UK. It was a sub-unit of the NPOIU, the Confidential Intelligence Unit, which ran a number of infiltrators that targeted protest movements.
The unit is notable for its targeting of the letter bomber Miles Cooper and the animal rights campaign Stop Huntingdon Animal Cruelty. However, it has run into controversy over the definition of domestic extremism, its monitoring of peaceful protesters and recording of details on its database, its links with industry and the activities of undercover officers it used to target various protest movements, most notably Mark Kennedy.
The National Domestic Extremism Unit page gives a general overview of the units dealing with domestic extremism.
