Well, I think yesterday was an important constitutional moment because all three devolved legislatures have now expressed their clear opinion in relation to the withdrawal agreement Bill. The debate that we had in this Chamber yesterday I felt set out very clearly the case for defending the constitutional rights of this establishment and the Welsh Government, and those of us who voted against the LCM yesterday did so for that reason. And I'm very pleased that the Assembly of the Senedd was so clear in its view. I think the UK Government should take note of that and should not proceed in the teeth of that opposition.

The Sewel convention provides, of course, that there were circumstances that may be not normal, and I'll take some comfort from the words in the Secretary of State's letter of Monday of this week that he would regard the circumstances as 'specific'. But I think it's undoubtedly the case that the Sewel convention is an important convention that, as currently designed, is not exactly fit for purpose. It provides too much discretion to the UK Government; it doesn't provide a sufficiently clear understanding of when it applies and when it should not apply. I think there's a case for going further than the convention to make it clear that the UK Parliament should never legislate when a consent has been withheld in relation to a devolved matter.

What I will say about the future of the union, and I've said it before—I think there are choices that lie ahead in the coming months, and the nature of those choices will affect the capacity of the union to survive. I very much hope that the Prime Minister will follow the direction of travel that we as a Government outlined in our publication earlier this week, because I fear that if we head down the road of a very hard Brexit, a very, very minimalist free trade agreement, the pressures that currently exist on the union will just be exacerbated.
