Brexit 10 Years On: UK's Economic and Political Shifts

AI Summary
Ten years after the Brexit referendum, the UK's economy is smaller than expected, migration is higher, and the country is falling behind its peers. The promises made during the referendum campaign have largely failed to materialize.

The Lead

On June 23, 2016, the UK voted to leave the European Union, marking a significant turning point in its history. A decade later, the consequences of Brexit are being felt across various sectors, from the economy to trade and migration.

The Event Details

The Brexit referendum resulted in 51.9% of voters choosing to leave the EU, while 48.1% voted to remain. The outcome led to a series of political changes, including the resignation of then-Prime Minister David Cameron and the ascension of Theresa May and later Boris Johnson.

The Data Analysis

The UK's economy has underperformed compared to its EU peers. Real GDP per capita has lagged behind the EU's 27 members, with the UK running five index points behind the bloc on a 2016 baseline. Economists project an average annual growth of just 1.3% between 2026 and 2030.

  • GDP per capita: The UK's GDP per capita was almost 30% higher than that of EEC nations in 1950, but by 1973, it was roughly 10% lower.
  • Business investment: UK companies pulled back sharply after the 2016 vote, with studies suggesting an investment shortfall of 12 to 18% compared to a non-Brexit scenario.

The Impact Analysis

Brexit has led to significant changes in trade, migration, and laws. The UK's departure from the EU resulted in:

  • Trade: Trade with Europe is on course to be about 15% lower in the long run, with trade deals with non-EU countries not making a meaningful difference.
  • Migration: Migration has not decreased as promised; instead, net arrivals from non-EU countries surged, pushing total net migration to a record high in 2023.
  • Laws: Thousands of European regulations applied automatically in UK law, but only a third have been amended or repealed.

The Prediction

Looking ahead, public opinion on Brexit has shifted significantly, with 57% of Britons now believing leaving the EU was the wrong decision. About two-thirds of 18- to 24-year-olds say they would vote to rejoin the EU. The UK's future relationship with the EU and its economic trajectory will likely continue to be influenced by these changing attitudes.
