This thesis delves into the depiction of the causes and consequences of the Brexit campaign and the impact on the personal relations and political attitudes of the characters in Jonathan Coe’s novel "Middle England" (2018). In the wake of rising nationalist and populist rhetoric delivered by the Leave campaign, the English society has become increasingly marked by affective polarization, that is emotional divisions between individuals or groups with opposing political views, while simultaneously becoming less tolerant towards immigrants. The thesis explores how Jonathan Coe, in the manner of a chronicler, offers a view of English society represented through an array of characters during a turbulent period in recent British history, when a set of arbitrary political decisions put a huge strain on their interpersonal relationships. Throughout the analysis, attention has been drawn to the position of immigrants and minorities in the context of British cosmopolitanism, but also to the challenges faced by the Eastern European immigrants who have moved to the rural parts of England as a result of the EU migration policies. The thesis also probes into the issues of nostalgia felt by some older characters who long for the England of their youth, mythologically represented as stable and a cohesive country that provided a sense of ontological security. The image of a conservative Albion is thus juxtaposed to a multicultural and cosmopolitan England that is ultimately shown as an illusion, since the intolerance that simmers just below the surface of civility is brought up by the Brexit referendum and the Leave campaign.
