This paper combines corpus linguistics and critical discourse analysis methodologies in order to investigate the discourses and cyber activism of the British right-wing nationalist party, Britain First. A study of a corpus of texts produced by elite members of the group reveals a racist, xenophobic stance which constructs Islam and Muslims as the radical, dangerous ‘Other’. This creates a discourse of fear that threatens the way of life of the indigenous in-group of the British people. An investigation of the cyber activity of the group demonstrates that Britain First is able to achieve a significant amount of following on social media by publishing populist material that veils their true nature or ideological stance.
