Well done for posting an article that comes up with next to no solutions as to how to solve the problems of exiting the customs union and policing the border. I guess that is what happens when you blindly post links to articles.
I particularly like this comment: "For large businesses, the UK has proposed that compliance checks should principally be carried out electronically, and where physical spot checks are needed, they should be done remotely, away from the border itself." These checks would examine compliance based upon certain standards - these would be EU standards.
Lazy posting. It would be better if you actually outlined what your solution is.
Alternatively, we could agree that being part of a group of nations with similar standards and shared interests that trading together under agreed tariffs and standards makes sense.
We are no longer an economic super power. Let's learn to play a part in the world more befitting of our stature and in the interests of our people. If we wish to walk away from the EU table - which is mad - then let's not walk away from the simplicity of a customs union.
