Well, I think the Member hits the nail on the head with his supplementary question, and I share his disappointment. It's now coming up to 15 months, actually, since the review of inter-governmental relations was commissioned. And the truth is that it's certainly not in the interest of Wales, but it's actually not in the interest of any part of the UK for the JMC structures to continue trying to bear the weight that is now placed upon them by Brexit in particular. I should say that the truth is that the First Minister has required more progress to happen than has happened. So, we are very disappointed with the level of—lack of progress, rather. The truth is there are—the constitutional ambitions, if I can put it like that, of the different Governments involved are different. There is no political leadership in Northern Ireland at the moment, and there has been the effort put into 'no deal' preparations. Official-level working has been good, but it's absolutely the case that not sufficient progress has been made. I would say that we've seen very little progress. I'm hoping to meet David Lidington later this week, and I'll be making the point to him that I'm concerned that there is no real commitment on the part of the United Kingdom Government to progress this.

He mentioned the principle of parity of participation in his question, which is absolutely fundamental to this. We've also talked about a mechanism for resolving disputes that introduces an independent element, so that, as his question implies, it isn't simply a matter for one part of the UK to determine the outcome. 

On the question of statutory underpinning, I think that could be usefully explored. I'm not sure myself that it is the panacea—what we need is robust structures. If it's also underpinned by statute, then that would be an advantage, but I think the key thing is to have in place structures that, frankly, work. I will also say that the format of the JMC, which is able, ultimately, to resolve this is the one between First Ministers and the Prime Minister. So, obviously, in light of the fact that the Conservative leadership is contested at the moment, that clearly is going to delay the point at which that format of the JMC is going to be able to meet to address this. But the next format of the JMC, on which I represent the Government, is intending to look at this point, at our instigation.
