The Supreme Court was right to make it clear that Parliament should exert democratic influence over Brexit. That influence should be felt at the start, throughout and, most importantly, at the end of the formal process of leaving the EU. In practice, the Opposition believe that there must be three distinct pillars of parliamentary scrutiny and accountability: first, the provision of a detailed plan published prior to the start of negotiations that can inform future debates and votes, and that can be used throughout as a point of reference; secondly, a means of ensuring robust parliamentary oversight throughout the formal negotiation period; and thirdly, a meaningful debate and vote in Parliament on the proposed deal before it is signed off with the European Council and Parliament.
