The graphic is interesting to be sure. But it states that "all 26 nations must agree on Brexit conditions". There are 27 member states in the EU as well as the UK. Schoolboy error.
This graphic emphasises how un-European the UK's position within the EU is. No Euro, no Schengen. I appreciate that tarrif-free trade was great for German car manufacturers and freedom of movement was spiffing for the hundreds of thousands of EU citizens who came to work in the UK every year but they will just have to adjust I guess.
