Steve,
If the elected government of the day promises to get us out of the EU come hell or high water if we tell them that's what we want, they are telling the voters that they are voting for an irrevocable decision. That is the covenant they made. The fact that they "forgot" to tell us that parliament may have to debate Article 50 first is a sideshow to that substantive matter. If you have a problem with that, Keith,

I do not have a problem with that. It is a fair description of the situation.
My problem was that you claimed to know all along that it was not an irrevocable decision.
