I am sorry if the hon. Lady is concerned, and I do not cavil at that: these are very important times for all of us. The answer is that there almost certainly will be a precedent, for the reason I gave to Kirsty Blackman from the Scottish National party a few moments ago, which is that there are precedents for most things in this House. If Catherine West is challenging me about when there was a precise precedent, I admit I cannot tell her. In fact, there will not be a precise precedent, because the particular circumstances of Brexit are a little different from anything else that has previously occurred. If she is wondering whether there has ever been such a situation, the answer is that there will have been precedents in the past.
What I am trying to do is to ensure that there is maximum time for those who care about these matters—I think a lot of Members do care about these matters, and may potentially have an interest in tabling an amendment and so on—and their interests will be protected by the Chair as effectively as I can possibly do so.
If there are no further points of order—I thank colleagues for their interest, and I hope to keep them updated—we come now to the second urgent question.
