The majority of MPs voted remain. But I doubt that they would flat out block brexit as that would not be acceptable. The smart money would be pushing the government for assurances on the terms. if they ditched the closed borders they would get access to the markets that are so important.I heard this back when the vote very first happened, then nothing more so I figured it was a "rumor."
How is Parliament situated? Will they allow the Brexit to continue?
Ironically the pound rallied today on news of the courts ruling.
It is all down to the European court of Justice to decide if parliament needs to hold debates or not, and their ruling will be final. Guess what that will be, and how it will affect Scotland and Wales
