Leaving the EU: Parliamentary Vote

There was a 72% turnout in the 2016 referendum. At the last election, the Labour party and the Conservative party stood on manifestos that pledged to deliver Brexit. With regard to the Scottish question, Scotland decided to stay in the United Kingdom. Is the point not that there has been a democratic opportunity and a once-in-a-lifetime referendum—interestingly, the Scottish referendum was supposed to be once-in-a-lifetime referendum? Does my hon. Friend agree that not to deliver on that would be an absolute betrayal of 17.4 million people, and of the 16 million people who took part on the other side of the referendum?
