The government's anti-radicalisation programme has decided worries about mass migration are 'terrorist ideology'.
Among the 'dangerous' beliefs flagged by Prevent's online training course are 'Cultural nationalism' and the idea 'Western culture is under threat'.
A statement on the official GOV.UK website describes 'Extreme right-wing' ideology as terrorism, before going on to list three sub-categories.
It says concerns around 'lack of integration by certain ethnic and cultural groups' are also a threat.
Critics have warned the definition of 'cultural nationalism' is too broad and could even encompass the likes of Sir Keir Starmer.
