This thesis investigates strategic media practices of the ‘new nationalist’ political parties in Western Europe. It provides an extensive literature review, interviews and a review of media artefacts, to establish how the parties have achieved substantial public support. It uses four case studies: the French Front National (FN), the Flemish Vlaams Belang (VB), Danish Dansk Folkeparti (DF) and the Europeanist-regionalist movement, Bloc Identitaire (BI). It draws on work by Cas Mudde, to define the parties as authoritarian, nativist and populist – ANPs. It describes their central concern with Islam in Europe (mass immigration, integration or otherwise of Muslim populations, and associated tensions), and their developing of the issue to gain support. The research concludes that the ANPs have been successful in campaigning through mass media to substantially improve their political position.
