Cue Brexit: Performing Global Britain at the UN Security Council

Abstract The role of performance in ontological security seeking is underdeveloped, despite the fact that many elements of such behaviour – narratives, rituals, routinised meetings – carry a distinctive performative quality. Drawing on Butlerian performance theory, this article makes the case that performances are essential to re-establishing coherence and a sense of self following ontologically critical situations. The reproduction of the self, especially while directly addressing fundamental existential questions, is an important way to overcome critical situations. At the state level, this reproduction of self also includes a reproduction of the international system, a task which is best enacted in everyday diplomatic practice. To explore this theory, I use Brexit as an illustrative case study. Brexit was a moment of profound crisis for the United Kingdom (UK) and an ontologically critical situation. It forced the UK to reposition itself on the world stage and confront significant challenges to its self-understanding. In Westminster, these efforts centred on ‘Global Britain’ – a narrative shift that bridged the identity gap and provided a thin framework for foreign policy. At the same time, British diplomats were tasked with international realignment post-Brexit. In this way, everyday diplomatic practice became Brexit performances.
