Yes, well, people on here were predicting this some considerable time ago.

I'll pick out some of the most pertinent parts, shall I?
"The UK is expected to drop out of the list of Germany's top 10 trading partners by the end of this year, official German statistics suggest.
Germans spent £13.8bn, or nearly 11%, less on British goods in the first six months of 2021, according to data from the Federal Statistics Office.
The UK has been in Germany's top 10 trading partners since 1950.
But with Brexit-related hurdles taking a toll, it looks set to drop to the 11th spot by the end of 2021."
"Before the UK voted to leave the EU in 2016, it was Germany's fifth most important trading partner.
But it came ninth last year and is now expected to fall another two places."
"Mr Schmidt said the new trade realities would have hit small UK companies more than German ones, as they were less accustomed to selling their goods outside the EU."
[Funny that, German firms being more accustomed to selling outside the EU than UK companies, despite being in the EU. Who'd have thunk it? Ed]
""For many small British firms, Brexit meant losing access to their most important export market," he said.
"It's like shooting yourself in the foot. And this explains why German imports from Britain are in free fall now."
Gabriel Felbermayr, president of the Kiel-based Institute for the World Economy, said: "The UK's loss of importance in foreign trade is the logical consequence of Brexit. These are probably lasting effects.""
[And the last sentence is priceless.]
"The Department for International Trade did not immediately respond to the BBC's request for comment."
