The basis, uncertain as it is, of what we have had so far is challenged by the very notion—as we keep hearing from the Government benches—that we need this to go into level 2. As Mr Macindoe has already said, we have already been in level 2 before. If this is a tacit admission from the Government that there was no legal basis from that then I'd rather that we had that conversation openly and honestly, and on a basis on which we can understand whether, in fact, such a piece of legislation as this is indeed required. And I note that legal academics have raised the question—I don't want to mischaracterise their position by stating it as anything other than a question—about the legal basis for what we have endured so far, but it's a fair question.
