The role of schools in developing a sense of common British identity has taken centre stage in the face of ‘racialised’ accounts of violence during the twenty first century. In this paper, we argue that certain British education policy documents can be understood as hegemonic interventions seeking to resolve ambiguities surrounding constructions of British identity. We do so by examining the Department for Education (DfE) ‘Fundamental British Values’ (FBV) guidance within the context of its relationship to the Prevent Duty anti-terrorism programme as well as the ‘Political impartiality in schools’ guidance released by the DfE in 2022. Utilising Critical Discourse Analysis (CDA) and applying Laclau and Mouffe (2014/1985) conception of hegemony with Hall’s (2021/2000) claim that ‘Britishness’ is an empty signifier, this paper argues that the ambiguities of ‘Britishness’ present a number of opportunities for power to be exercised and consolidated. Finally, we explore the possible implications for demands to ‘decolonise the curriculum’ within schools’ existing duties and propose possible structural limits placed upon these demands by said duties.
