Re: What a horrible waste of time and money
Could be irrelevant anyway. Just because a majority of MPs backed remain up to the referendum does not mean that they would want to block the expressed will of the people. Any MP in a constituency that backed Leave could pretty much kiss goodbye to his job if he voted against triggering Article 50, so I'd say it's quite likely that Parliament would pass it, if it came down to it..
P.S. your link didn't work for me, I found this link - Nick Barber, Tom Hickman and Jeff King: Pulling the Article 50 ‘Trigger’: Parliament’s Indispensable Role - instead.
