This is just manipulating the vote and splitting the leave vote so remain wins. I am against a second referendum of all sorts and think we should leave deal or no deal on 31 October. However, I can see that the remain majority parliament will never accept leaving and the establishment, whether it be big business, bankers or the legal system will throw all of their weight behind stopping it as we've seen.
So, maybe we do need a second referendum. As all we keep hearing from those who want a second referendum is that, it's not that they don't accept the first referendum, they just want the people to have a final say: let's let the people have the final say. As is their wish, we respect the first referendum and we have a final say second referendum, which is in the last week of October. In the meantime, Boris and his team negotiate a second deal with the EU over the next month and we continue our final preparations to leave with no deal.
Come the end October, we have a second referendum with the two choices: leave with Boris's deal (with the "backstop" being Theresa May's deal, if there is no new deal agreed) or leave with no deal. We leave on 31 October regardless.
As I say, not a route I think we should need, but it would be a good way of calling the bluff of those remainers who keep saying they accept the original referendum and don't want to overturn it, but just want a say on the final deal.
