I find myself in rather a strange place because it is very difficult for somebody in my position to countenance voting for an Opposition amendment. I have always respected the pragmatism and politics behind most decisions, but I have always had a sneaking admiration for colleagues who flouted the Government Whip with impunity, which was not, of course, what I told them when I was in the Whips Office. I heard in so many cases that their decision was a point of principle. Indeed, the Secretary of State for Brexit was among the most principled politicians in the last Parliament, rebelling dozens of times.
To me, this is very much a point of principle, and three principles have exercised me and many colleagues. The first is the thorny question of what parliamentary sovereignty means. Far be it from me to take exception with that very learned gentleman, my hon. Friend the Member for Esher and Walton (Mr Raab), but my understanding is that article 50 was effectively drafted on the back of a fag packet by negotiators, specifically at the request of UK participants in the treaty, on the expectation that it would never be triggered; such a situation was inconceivable. Therefore, it seems not inconceivable to set out what we believe our sovereign parliamentary process should be against that rather poorly drafted aspect of the treaty.
So many leave campaigners told me that they were campaigning to restore our sovereignty. That sovereignty has now been confirmed by the Supreme Court. It is absolutely right that we have had confirmation today that Parliament will have a vote on the terms of the deal. The timing of that vote is crucial. It will not be a done deal that is then brought back to us. There will be an opportunity to influence, shape, negotiate and do what we have done so well over the past four days—days, by the way, that we were not intended to have. We have had the opportunity to get into the nitty-gritty of what it means to trigger article 50, and what a vote would look like. I, for one, feel far better informed than I did at the start of the process. This is exactly what we are sent here to do.
