European Union (Withdrawal) Bill

Could I just clarify something with the noble Lord? I am very sympathetic to what he is saying, but he has twice said, “We all know what a bad deal would be”. But we do not. I suspect in a few months’ time that we might regret not appreciating that we need some criteria to judge what is a good deal and what is a bad deal—whether, as some people might think, it is single market, customs union or whatever. Unless there are some criteria against which we can judge the outcome, we will be all over the place, which could lead to a very interesting debate on Report on this very question of a mandate.
