Terrorism
The current UK definition is set out in the Terrorism Act 2000 (TACT 2000). In summary this defines terrorism as 'The use or threat of serious violence against a person or serious damage to property where that action is:
designed to influence the government or an international governmental organisation or to intimidate the public or a section of the public; and
for the purpose of advancing a political, religious, racial or ideological cause.'
Extreme Right-Wing Terrorism (ERWT)
Describes those involved in Extreme Right-Wing activity who use violence in furtherance of their ideology. These ideologies can be broadly characterised as Cultural Nationalism, White Nationalism and White Supremacism. Individuals and groups may subscribe to ideological tenets and ideas from more than one category.

MI5 and Counter Terrorism Policing (CTP) continue to use the Extreme Right-Wing Terrorism
(ERWT) ideological categories defined by the Joint Terrorism Analysis Centre since May 2019
(White Supremacy, White Nationalism, and Cultural Nationalism) as a pragmatic way of
efficiently describing the complex, shifting, and sometimes overlapping grievance narratives
sitting within the ERWT thematic. However, each individual or group that they investigate is
judged on the specific terrorist threat and risk they are assessed to pose, and charging decisions
are the preserve of the relevant prosecuting authority, informed by evidence collected and
presented by CTP.
