"Why does it matter, some may ask, that parliament is involved in the UK’s exit from the EU? Why not just leave it to the government to use its executive power? After all, we know that in recent years governments have agreed not to declare war or commit our troops to overseas engagements without parliamentary scrutiny and approval.
Commons votes were held in 2011 on our involvement in Libya, in 2013 and 2015 on involvement in the Syria conflict and against Islamic State in Iraq. I would argue that in terms of our country’s international profile, Brexit is just as significant a development as any military engagement.
Parliamentary sovereignty – the right to pass laws as the supreme legal authority in the land, including laws that limit the powers of the executive – has been hard-won over hundreds of years. We trample on it at our peril. It may be Brexit now, but what next? Who is to say what element of our constitution could be questioned in future?"
