Yes, I've read it. 

I see an assertion but no actual evidence and frankly it's far too early for there to be any evidence. There was massive stockpiling during December too in anticipation of problems when Brexit finally came in and that will have had some effect.

I also see that the biggest port presents a different picture, though they do confirm that some trucks have been turned away because their paperwork was incorrect. 

I expect that coronavirus has had its effect too. I note that France is demanding PCR testing for lorry drivers before they allow them in. Unlike the lateral flow tests, the PCR can take a couple of days before a result is available. 

In these circumstances, if there are delays, then what the Hauliers Assoc are doing is  getting in their excuses and saying 'It's not our fault, Guv."
