The issue of compliance raises a very simple question. I say this to Keir Starmer: it is by no means certain that the law of the land is reflected in the passing of the European Union (Withdrawal) (No. 2) Act, because there is an apparent inconsistency between that Act and the European Union (Withdrawal) Act 2018. I have no time to go into the details, but the reality is that compliance is not just a simple question. It is a matter of grave importance in terms of which law is the law of the land.
