@codejunky - "It was promised to be implemented though."
No it was not - The referendum was not legally binding, as such Parliament is not obliged to follow it through. Likewise 75% of the Leave "facts" have since been disproved, and the circumstances of our departure are not was promised - With all things of significance, there should be sanity-checks before acting - As such, what is the problem with having a confirmation-referendum?
People can bitch all they like, but the corner stone of democracy is the ability to change ones mind. As many people point out, there are people who voted who now regret their vote, but flipside, I know of people who voted remain who now wish to leave!
One of the beautiful things about democracy, is the ability to change ones mind
