Obvious only to your typical, prissy, toys-out-of-pram-when-I-don't-get-my-way loony lefty bent on making Britain a non-country. A referendum should only be used on the terms of a deal/no deal scenario. Just accept it and move on already. Mess with the decision, you'll stir a hornets nest and the country will forever be divided. Surely even the dippiest, most selfish of unpatriotic 'Brits' can see that?
