Brexit: Assessing the UK-EU Relationship Years After the Split

The United Kingdom’s departure from the European Union, commonly known as Brexit, formally took place on January 31, 2020, after a referendum in 2016 where 52% of voters opted to leave Britannica. While the initial withdrawal date marked a significant turning point, the subsequent years have been characterized by ongoing adjustments, negotiations, and a complex evolving relationship between the UK and the EU.

The Road to Brexit

The decision to leave the EU followed decades of debate regarding the UK’s membership in the European project. The UK initially joined the European Economic Community (EEC) in 1973, and over time, its relationship with the evolving EU became a source of political division.
