The argument that voters were ignorant of any 'deal' when the voted is entirely spurious, and the sort of nonsense the Remainers love to spout.
History will show that the electorate voted on a straightforward question - Do you wish to leave the EU - yes or no?
It really couldn't be much simpler than that - so where they get the 'people didn't understand … ' garbage from is anyone's guess.
The simple fact is, no 'deals' were available at the time, because negotiating a deal could only ever begin if there was a vote to leave, otherwise what would anyone be 'dealing' about?
To say that the electorate did not understand the 'deal' is simply not true - there was no 'deal' - the vote was to leave or not, the rest is about the terms of departure, not whether we leave or not, that has been decided - remember? There was a vote???
