UK leaving the EU could be a messy divorce: Polls

When Britons decide next week whether to leave the European Union the question will be simple: yes or no. Actually leaving would be far more complicated, rather like a drawn-out, painful and possibly bitter divorce.
Opinion polls suggest it could go either way on June 23, when Britain chooses whether to leave the 28-nation bloc it joined in 1973, with undecided voters likely to make the difference.
As luck would have it, a new and never before used "exit clause" in the EU's rule book allows any member to withdraw. On paper, it looks straightforward. But of course it's not. And should it be time to say goodbye, the way the process unfolds will have deep ramifications for Britain and probably influence what happens to the EU down the road, experts say.
Britain wouldn't leave the EU immediately. It would remain for up to two years while it unpicks its relations with the continent. If needed, it could even ask for an extension beyond the two years, but all 27 countries would have to agree.
In that period, British Prime Minister David Cameron, or whoever succeeds him, would have to draw up with his counterparts the arrangements for the country's departure. The terms of that accord would have to be accepted by a majority of about two thirds of the EU countries.
The sides would have to decide, among other things, on whether Britain remains in the EU's single market or will be subjected to new tariffs on trade.
This is when the remaining EU countries could make life very difficult for Britain. How tough the negotiations get would determine the future for both sides.
Some say the Europeans won't be doing Britain any favors. Given the number of crises in Europe - economic stagnation, the refugee emergency, extremist attacks - it's hard to see why members would take the time to negotiate in good faith with a partner who's deserting them. The leaders may have already expended a lot of their goodwill on the special concessions they agreed on earlier this year to persuade Britain to stay.
"It would be in the interest of the rest of the EU to make sure that this does not create a precedent," said Fabian Zuleeg, chief executive at the European Policy Centre in Brussels.
Few would relish the thought, he said, of "a country outside that has some sort of pick-and-choose, associate membership which could look quite attractive for a number of other countries."
Tough negotiations could mean legal and investment uncertainty and might see Britain excluded from the European single market. Cameron dearly wants to avoid being shut out.
