Why did the United Kingdom leave the European Union in 2020?

The United Kingdom’s departure from the European Union, known as Brexit, was initiated by a national referendum held on June 23, 2016, in which 52 percent of voters chose to leave the organization.123

The decision was driven by several key factors:
* Sovereignty and Regulation: Many proponents of leaving argued that the U.K. had ceded too much sovereignty to the EU and were frustrated by regulations on consumers, employers, and the environment, which they claimed hindered the British economy.45
* Immigration: Concerns regarding the influx of migrants from other EU nations, facilitated by the EU’s open-border policies, fueled anti-immigrant sentiment.45
* Financial Obligations: Euroskeptics were alarmed by British financial contributions to the EU, particularly regarding bailouts during the euro-zone debt crisis.45
* Trade: Pro-leave advocates argued that EU membership prevented the U.K. from negotiating its own advantageous trade deals independently.45

Following the vote, the U.K. formally withdrew on January 31, 2020, after years of complex negotiations and domestic political shifts.126
