Abstract
At a practical level, the findings of the research reported in this thesis are discussed in terms of the potential role powerful anti-EU discourses have in accentuating perceptions of incompatibility between British national and European identities, and levels of national identity tlueat. At a theoretical level, the findings are discussed in relation to the utility of including identity content in cross-level social identity investigations, the distinction between intergroup distinctiveness threat and group distinctiveness threat and the structural representations used to symbolise the relations between cross-level identifications.
