People are saying that the Tories are going to vote for May's deal, and then "crash out" at the end of the transition.
People so overheated with paranoid orgasm that they don't think.
There is a clause in the withdrawal agreement that we cannot leave. If negotiations fail completely to produce any new terms, there is STILL a base limit to how far we can leave.
The backstop - you must have heard of it - is a clause that comes into effect should it prove impossible to reach any further agreement.
But all this is reason not to have referendums. People will not know what they're voting for and they do not pay attention.
