"Once buttons have been pushed," Keith. The button is Article 50. No going back once that has been kick-started, despite what Teribus sez. Irrevocable. As far as I can see from here, that is a rock-solid cert. This is not about not doing it. It's about doing it properly. Rule of law, Keith. In fact, to all intents and purposes, the "decision of the people" (all 37% of them) was always intended to be irrevocable. I can't see that anything that's happened so far has changed that, certainly not the court judgement, which had nothing to do with whether brexit happens or not. The referendum was advisory but the government was, and still is, determined to be driven by it. There is, sadly, no political groundswell for overturning it. In effect, as soon as the result was known, the decision was irrevocable. Nothing to do with "advisory" or not, everything to do with politics. The government simply decided, ahead of the vote, to take the advice, whatever it was. Sorry you felt you had to waste all that time nitpicking. Keeps you off the streets, I suppose.
