No, if there's a vote of no confidence in the government, then the leader of the opposition is given a chance to form a government, or anyone else after that if they can't. they have two weeks to sort it out so that a majority of parliament will vote for someone, if not then there's a general election. so in theory there could be a temporary government of national unity type deal, e.g. with the sole purpose of legislating for a new referendum, after which there'd be a GE. all quite unlikely, but it's one of the few remaining ways out of this mess.
