This is the first comparative study of the distinctive literatures and cultures that have developed in Wales, Scotland, England and Northern Ireland since political devolution in the late 1990s, especially surrounding Brexit. The book argues that in conceptualising their cultures as 'national', each nation is caught up in a creative tension between emulating forms of cultural production found in the others to assert common aspirations, and downplaying those connections in order to forge a sense of cultural distinctiveness. The author explores the resulting dilemmas, with chapters analysing the growth of the creative industries; the relationship between UK City of Culture and its forerunner, the European Capital of Culture; national book prizes in Britain and Europe; British variations on Nordic Noir TV; and the Brexit novel. With regard to separate cultural precursors and responses in each nation, Brexit itself is debated as a factor that has widened their differences, placing the future of the UK in question.
