European Union (Notification of Withdrawal) Bill

There is something I do not understand— I have been thinking about it since it was raised by the right hon. Member for Normanton, Pontefract and Castleford (Yvette Cooper). The hon. Gentleman asks whether we could have a vote in a situation of not having a deal. The leader of the Liberal Democrats has been clear in his view that if we said no to the deal, we would remain in the European Union. In a vote in a no deal situation, what are the two choices? Would one of them be remaining in the European Union?
