To leave, or not to leave: More than two and a half years since the United Kingdom voted to exit the EU, that is still the question.The crisis in Prime Minister Theresa May's government over her draft Brexit divorce deal has stirred interest in the possibility that the United Kingdom could change its mind, or 'regrexit'.In the June 23, 2016 referendum, 17.4 million voters, or 52 percent, backed Brexit while 16.1 million, or 48 percent, backed staying in the bloc.
