From the article:
"The first year of the pandemic damaged the UK more than most economies. This was the textbook expectation from many economic experts of the government's approach to post-Brexit policy. It is more difficult for small businesses, especially, to trade with Europe, and the UK, by design, now has more limited access to pools of European workers. As a result the economy is less productive, less resilient, less flexible and less responsive."
From time to time the BBC reports a bit of #brexit truth.
