"I made the argument last week that the EU was a protectionist gravy train"
You may well have done, but your voice may have been muffled if you were sitting down. The EU does what any trading block does, it protects its members. So the EU has rules that permit the free movement of goods and service *between members*. Those outside the EU have to take a back seat, which is true for any similar trading block such as NAFTA or TPP.
May one suggest that you cease to read the Daily Mail?
