If you are really that hung up about Europe - then get out and do absolutely no trade with Europe at all - and that includes finding alternate import and export routes - no dealing with Euro and Sterling - and no flights from UK to land at any EU airport and no EU flight to land in UK - This is a true out of Europe Scenario - but of course Britain wants the best as ever from every country - even the CROWN JEWELS - THE KOHINOOR WHICH SITS ON TOP OF THE QUEEN'S CROWN HAS BEEN STOLEN - FROM INDIA !!!
