Totally agree.
This is a cost of Brexit, which we are choosing not to implement... because it would cost too much, interfere with food imports etc. Meanwhile... UK exporters DO have to go through all these steps and requirements to export to the EU, meaning that as a result of Brexit, it now costs us more to import... whereas the EU can now import into the UK without that same cost - i.e. it means the farmers now face unfair competition.
This is above and beyond the cost that the various ports have had to pay to actually set up all the buildings etc.
This is scarily what the remain campaign mentioned would happen (increased friction on imports and exports) before the vote... and now we have the Minister for Brexit Opportunities claiming this is a benefit?? Weird weird world!
