Some thoughts on questions raised by Jim and others; what IS Brexit? what should Parliament's role be in implementing it?
The referendum options were to remain in the EU or to leave it. Leaving it means repealing the law that took us into the Common Market. Once out the UK is not compelled to accept law and regulation formulated in Brussels, and British courts can no longer be overridden by the European Court of Justice. That to me is Brexit. The government's promise was that they "will implement the people's decision". That was an unqualified commitment. There were many arguments for and against, prominently about the free movement of EU workers, but these particulars were to be found in the manifestos of the campaigners and NOT in the referendum question on which we voted. So I disagree with trying to get inside the heads of the voters to guess what their definition of Brexit was and their reasons for voting as they did; Brexiters have the right to ask, but not to demand that specific agenda are part of our leave deal with the EU. If, say, (not that I think this will happen) the government accepts free movement as the price of remaining in the free market it will disappoint a lot of people (me for one), but it will not (in my opinion) be a betrayal of the leave vote. Future governments will be free to renegotiate that agreement or withdraw from it.
Parliament's role in Brexit? Described by Jim as a possible "clash between two forms of democracy". I see the clash, but prefer term "expressions of" to "forms of". Not trying to be pedantic. I am against the principle of "direct-democracy" which invokes the popular vote to decide all "important" issues, and am for parliamentary democracy so, on the whole, against referendums. But there are cases when a nation is faced with a political decision (do we or do we not?) which may change its future for generations to come. Entering the Common Market was one such. There may be deep convictions and violent passions on both sides and these differences may not align themselves along traditional party lines. Whatever and however the issue is decided everyone will have to suffer the consequences be they for better or for worse. That's the case for deciding the issue by a simple majority decision. On Brexit we have that decision. I'd like to see the "winners" more magnanimous in victory than some of us have been so far, and some of the "losers" (I believe, certainly hope, by the way, that we will ALL be winners from Brexit) being more gracious in defeat. As for Parliament I agree with Jim that both Remainers and Leavers inside Parliament should continue to argue their points of view, BUT about the hows not the fact of Brexit. The reality, however, is that the terms of our future relationship with the EU will be determined largely by the EU, not by the government or any faction in any party.
The dangers I see in Jim's "clash" are twofold. Hard-line Brexiters may delay our exit if, say, they think the government has offered too many concessions on free movement in order to get better trading arrangements with the EU. The greater danger, however, as I see it, is that hard-line Remainers in both chambers may impede exit by opposing the Great Repeal Bill.
