Again, "strangely" specific.
Britain's Total World trade balance is much worse than in 2016
(Also and on your mentioning of falling EU trade, it's hilarious that you think that "losing more of those clients we've already been losing" is somehow a good thing. Yeah, sure, that makes total business sense mate ... wanna buy this river crossing property I have for sale in a major US city?)
You see, Non-EU Trade was also affected by Brexit due to the loss of all those Trade Treaties that Britain had via the EU and which the country had to try to replace because it left the trade block. Back in the Referedum days we were all told how "sovereign Britain" would be able to negotiate even better trade terms than the EU and here we are, almost a decade later, and Britain failed to negotiate replacement for all those trade treaties, much less get better trade terms in those it did (as expected: the other countries will concede much better trade terms for access to a trade block of 540 million people than for access to a country of 40 million), hence its trade balance with the World has never been this bad.
(Surely, "The Brexit Dividend Is Just Around The Corner And Will Begin At Any Moment Now" just like Brexiters have claimed since 2016)
The CAP stuff is also a hilarious obcession, given that British agricultural products are part of those "goods" where trade balance has worsen steeply, so clearly leaving the EU and the CAP didn't turn out so great for British farmers.
Also, it's been hilarious to watch Britain weaken it's own food safety legislation rules - "overregulation" being the main argument from Brexiters for the CAP being a horrible thing - further shafting the entire Food Production For Export sector in the UK AND weakening the quality and safety of the food that Britons consume thus also shafting everybody living in Britain (all of which, on a personal note, periodically reminds me that leaving Britain after Leave won was one of the best decisions in my life).
Trully an amazing Leave achievement!
Congratulations for shafting British food safety and the trade prospects of the British Food Sector including British Farmers so as to get rid of pesky EU Agricultural Regulations. Brits finally will get to enjoy the pleasure of eating Hormone Beef and Chlorinated Chicken (with its many times higher rates of Salmonella)!
