To leave, or not to leave: 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, voted to stay in the bloc.
