@centrox,
Still, I don't see a viable path out of brexit anytime soon. It would take May's resignation for a start. Then the next PM would have to be enough of a remainist to call for another referendum... The whole scenario seems highly unlikely to me.
More probably, negotiations will proceed at a very slow pace and no deal will be reached in two years. Then the UK will ask for more time, and if the other euro nations agree, the negotiations could last forever... until such a time when scenario 1 above could crank in.
Whatever the outcome, it'll involve pretty humoungous waste, generated by a penny wise pound stupid approach to international relations. This whole blackmail approach by whathisname the previous PM was so petty, narrow-minded and contemptuous of other EU members...
Obviously, the UK needs to learn a little humility, and the other nations will make sure the UK learns as much of it as it possibly can...
