It has been four years since the United Kingdom left the European Union. This has - so far - not achieved what many British people had hoped. No longer following Brussels' lead was supposed to be good for the economy. But there is not much to show for the departure yet. 60% of British people would prefer to return to the EU. According to the IMF, the United Kingdom's economy will grow the least of all the G-20 countries in the coming years.
Since leaving the EU, there is no longer free movement of people and goods. Now trade is conducted as prior to joining the EU: with import tariffs and customs controls. If you want to work in the UK, you (usually) need a visa.
The outcome of Brexit has been disappointing so far. But you can also look at it differently. Critics predicted that the British economy would collapse. That certainly did not happen. The British economy is reasonably in line with the economy of continental Europe. According to the Office for National Statistics (ONS), growth in the UK economy was +0.4% in 2023. That's not much, but it is higher than, for example, Germany, which fell into a recession.
Brexit has mainly led to a lot of uncertainty among companies and investors. This is reflected in both private consumption and business investments. These fell sharply in 2023. It is mainly foreign trade that keeps the British economy afloat and that in itself is remarkable after the departure from the EU (which resulted in barriers to trade with Europe).
