Actually this gives me an idea. I've just solved Brexit!
We have the so-called "people's vote". Ugh! As if calling things the "people's anything" isn't automatically either nauseating or suspiciously dictatorial. See People's Princess, Democratic People's Republic of anywhere.
So we have the vote and the question is simply:
Are you sure?
OK
CANCEL
For extra fun we don't tell people what either of these two options mean, and the Queen then just tosses a coin and either enacts a law cancelling Article 50 or allows no-deal Brexit to happen as is the current default.
This is transparent, democratic and simple. Everyone's a winner!
