I don't know if it's true or if it's an Assembly myth, Llywydd, but I'm told that if you stand on that piece of glass in the middle of the Assembly Chamber, it will crack and let you fall into the fault that lies below. I don't know if that is true or not, but the debate here—[Interruption.] I'm not going to try it, don't worry. You can try it, though, Alun. It would be a good place for you to go. Go on, have a go. [Laughter.] But the debate here today has definitely shown a fault between those parties here who believe in the indelible rightness of parliamentary sovereignty at a UK level, and those of us who have spent our political lives questioning the ability of the British constitution to deliver for the people of Wales. When the Cabinet Secretary first introduced his statement on this agreement, I challenged him at the time, and I said I thought he had a touching faith, I think I put it, in the UK constitution. Over the last couple of weeks I think that touching faith has been revealed, but I think all the weaknesses have been revealed as well.
