Brexit is a constitutional, legal, and political challenge of a size the UK has not seen in decades and will have consequences that are both uncertain and long-lasting. In this post, Dominic Grieve offers his distinctive perspective on Brexit, discussing the concept of parliamentary sovereignty, the role of international courts in UK law, and the more troubling aspects of the Withdrawal Bill itself. 

The EU and the sovereignty of parliament

My Brexiter colleagues have in varying degrees signed up to the view that EU membership undermines the sovereignty of parliament in a manner which is damaging to our independence and our parliamentary democracy.
