It is perfectly appropriate, although I do not like the word “appropriate”, as we all know. Perhaps the answer is that it is not necessary, but it may be appropriate.

Brexit, even though some people still hope that we will not go that far, and it has therefore served its purpose. I am not making a legal analysis of whether the conditions in the Act apply because I can see arguments why they may and why they may not; I am explaining why, if there is a suggestion that this House will vote for a referendum, it would be better to do it on an amendment or a Motion that directly raises that question. It can then be fully debated and we can all have our say. For those reasons, I very much regret to tell my noble friend that I cannot support his amendment.
