UK would face tough choices after a Brexit vote

By William Schomberg LONDON (Reuters) - Britain will need to make choices on trade, labour laws and the environment that could be unpopular with voters if it wants to offset the hit to its economy from any decision to leave the European Union, a think tank said on Wednesday. Britain's economic output would probably be between 0.5 and 1.5 percent smaller than it would otherwise be by 2030 if it decides to quit the bloc in a referendum in June, according to Open Europe, a pro-market research unit.
