The pound has been 20% overvalued for 30 years? I'm struggling to see why being outside of a large trading bloc is better than being inside a large trading bloc. You've said it is better off long term so there must be advantages to being outside. EDIT Just to clarify the UK exports much more in services to the EU than it imports from the EU. Services are exactly the type of thing that the EU is different from other trade deals. The UK loses what it has a surplus on and has to pay more for all the goods that it has to import.
