Why the hell would we give Parliament 'a say'? We elect Parliament to do the boring business of everyday government because we're all too busy doing real jobs. For something important like Brexit we voted on it directly ourselves, and a decision was made.
The idea of Parliament overturning Brexit is like an important businessman telling his secretary that Joe Bloggs can't have a raise, but the secretary decides to give him one anyway. Later that week, as the secretary is being sacked and unceremoniously escorted out of the office by security, their wailing and cries of 'But I normally handle the payroll for you! Why are you sacking me?' echo up and down the office, as a warning to the rest of the secretaries lest they start thinking they're running the company.
The secretary later goes home to their apartment and slits their wrists in the bathtub. The obituary is short, and merely reads 'Ed Milliband tragically committed suicide after losing his job for gross incompetence. Again.'
Covenant with the strawman, ftw.
The question in the referendum was, essentially, "do you want to leave the EU?" not do you want to leave the EU but remain in the single market? What about border controls? Various taxes? Human rights?
Are there going to be referenda on that? No. That's why parliament wants to have a say. They might try to stop Brexit, but taking Labour's ridiculously stupid move after the vote, MPs tried to oust their leader, who was voted in by members of their party, and the members of their party voted him back as leader, and I find it hard to believe anyone can honestly expect an elected representative to say "nah, the people don't know what they want" and have them still be an elected representative. That shit won't fly. People know how to use social media, there'll be lists of MPs that go against the vote going around faster than a cat video.
... Remain and were decisively defeated...
lol 1.9% is decisive.
Remember when Farage was all "we won't accept a 52/48 split"?
Anyhow, my position:
May has said there's going to be no running commentary on their negotiating position. Far as I can tell, even four months hence, there has been no commentary whatsoever. Parliament shouldn't have any say on whether or not the UK leaves the EU, since folk already voted for it - however thin the margin. They should, however, be able to represent their constituents by having a say on whatever terms the UK should push for in the negotiations.
Not everyone voted for the Tories, but as things stand, the Tories are now negotiating for everyone, despite the aforementioned vagueness of the referendum question. Representative democracy ftw.
