anyone who says "things will continue as usual " is wrong
if we leave then NEW argreements have to put in place - the old ones are based on the fact we're in the EU and apply to all countries.
When we're out any new agreement will have to be ratified by ALL those still in - and I can see a few people holding a teensy-weensy grudge against the UK for putting them through this ridiculous fandango
Plus the likes of Air France & Alitalia will be looking to knock back every UK LCO........
