The obvious book to read is the ‘Book of Countries Which Have Left the EU’. It is, alas, both short and written in Inuit. With no country other than Greenland ever having left the EU, there is little precedent to go on. Greenland has many differences with the UK which render meaningful comparison impossible – that it has a population of some 50,000, and no roads between its cities being two. The fact that while Greenland left the EU, its monarch (it shares one with Denmark) is still in it may also prove to be different than what would happen in the event of Brexit, though if Scotland secedes from the UK to remain in the EU, perhaps it might not be so different after all.
