Fleurpepper
The UK has many problems other EU countries do not have. No longer part of the massive and influential European Medicines Agency, that are able to negotiate en masse. The UK has problems with red tape and import and exports via Europe, as well as transport issues. All directly linked to Brexit.
The UK also has issues with the tanking pound, which has lost so much value due to exchange rate. The UK has to pay much more than other countries just due to low Sterling value.
That article states what we already know though Fleurpepper, it doesn’t say that the situation is ‘much worse’ in the UK, it acknowledges that many countries are having similar issues. I’m not defending Brexit, it was a disaster, and will have a definite impact on supply - but you are using hyperbole which is not backed up by evidence to describe the reality of the situation.
