In the new age of globalization, regional integration has become necessary for nation states to achieve their collective cum individual objectives in their relationship with one another. The formation of EuropeanUnion as a regional organization came at a time Europe was a theatre of conflict and wars. The ravaging effect of the Second World War spurred the proponents of European Union to seekcloser integration of neighbouring economies.This initiative was to support economic growth strategies, greater social equality, better trade relations and democratization.To substantiate this proposition, this study examined European Union, its structure, composition, cardinal objectives, British involvement and exit from the Union and the imperatives of her national Interest as a nation state. The data for the study were gathered from secondary source of data, these include textbooks, journals, newspapers, periodicals and other relevant publications. The study discovered that Britain has been an awkward member of the EU since she joined the union which has put her national interest in jeopardy and as such has led to unhealthy relationship within it. Eventually, “Brexit” became imperative for United Kingdom in the primary interest of the nation and solemn pursuit of her foreign policy objectives in global politics.
