May I make some progress at this stage? I will certainly invite the right hon. Gentleman to intervene later, but I want to develop my arguments on the clauses.
Clause 2 preserves the domestic law we have made to implement our EU obligations. More specifically, the clause will preserve any domestic regulations made under section 2(2) of, or paragraph 1A of schedule 2 to, the European Communities Act 1972. Without clause 2, such legislation would lapse at the same time as the repeal of the 1972 Act, meaning that there would be substantial holes in our statute book on the day we leave the EU. The clause is therefore essential to preserve our statute book and provide certainty over what our law is. I think that all Members would agree that at the heart of the rule of law is the need for certainty. That was why the Prime Minister put that at the top of her list when she outlined her criteria in the Lancaster House speech, and it was why I campaigned very strongly on that when standing for re-election.
