Obviously the scenario you paint is utterly unacceptable. As would the drugs and guns smuggled from south America and eastern Europe and appearing on the streets of Glasgow and London. As I provided previously there are 5 viable solutions (6 if one includes Tommies highly impracticable one. )How would that work? Dont forget our 'wonderful' Mr Liam Fox is intending a free trade deal with China....how would the EU react to goods coming in tariff free into Belfast from China and then being sold into Ireland across the 'no border'....we are discussing this on a site for pedelecs,it could be that post Brexit e-bikes coming into Dublin would be subject to maybe 54% duty,those into Belfast tariff free...that would have Juncker spilling his finest!!!!
Even if we crash out,the WTO tariff I think is 14%,a lot less than 54%.
KudosDave
A UK crashout is increasingly likely due to the confusion around the uk cabinet table.
As a compromise, Ireland could host one if the border posts for south Wales. Our port at rosslare has the necessary space and infrastructure to handle traffic from swansea and Pembroke.
In the model I was suggesting, for cairnryan liverpool etc. All trade would go through a joint border customs post manned by both uk and EU officials, and all international trade by sea would be dealt with it there. In Ireland we are familiar with this concept as we have US customs and immigration for air passengers at Dublin and Shannon airports. In these US personnel , with american accents , carry out us immigration proceduress while on irish soil.
