This paper reviews the deeper societal and economic reasons behind the British choice of leaving the European Union. We address the detailed results of the referendum and the long-standing sceptical British attitude towards European integration; next, we analyse the net budgetary contribution that changed enormously after the Eastern Enlargement. It is argued that the rise in the immigrantnative ratio had a significant impact on employee’s pay level in certain areas, therefore pro-Brexit campaigners highlighted migration as one of the major problems arising from EU membership. Increasing income and wealth inequalities and a growing anti-elite sentiment in British society, coupled with the negative image of Brussels bureaucrats and a British approach to the rule of law that is fundamentally different from the continental one, also contributed to the final result of the referendum. Our analysis ends with a glimpse into the close future, emphasising that the future of British-EU relations depends wholly on the pragmatism and wisdom of the negotiating parties.
