It is included here as it is one of the key legal documents relating to the prevention of extremism and radicalisation in the UK.
The Counter-Terrorism and Security Act 2015 contains a duty on specified authorities to have due regard to the need to prevent people from being drawn into terrorism.
The government has produced guidance (issued under section 29 of the Act) for specified authorities, which they must have regard to when complying with the duty. There are 2 versions of the guidance: one for authorities in England and Wales, and one for authorities in Scotland.
