Proscribed Organisations

The Home Secretary may proscribe an organisation if they believe it is connected to terrorism.

They can do so under the Terrorism Act 2000. This means that the group/organisation:

  • commits or participates in acts of terrorism;
  • prepares for terrorism;
  • promotes or encourages terrorism (including the unlawful glorification of terrorism);
  • or is otherwise concerned in terrorism.


When an organisation/group is proscribed, it makes it a criminal offence to:

  • belong to or invite support for a proscribed organisation;
  • arrange a meeting in support of a proscribed organisation; and
  • wear clothing or carry articles in public which arouse reasonable suspicion that an individual is a member or supporter of the proscribed organisation.


An up to date list of groups and organisations that are proscribed in the United Kingdom can be found on the Government website www.gov.uk

The Home Secretary can add or remove groups when required.
