Yes, I agree with that. The principle ought to be one of collaboration, and it ought to be one that proceeds on the basis of a parity of esteem and parity of participation across all four Governments in the UK. There may be a hierarchy of Parliament under the constitutional theory of the UK, but there actually isn't a hierarchy of Governments, and Governments should be treated as equals in those discussions. 

In relation to the negotiations that he refers to specifically, he will know from our discussions in committee that we are very disappointed about the lack of genuine involvement in that, even in so far as they relate to matters that are devolved. But, again, in that context, we, as a Government, have taken every opportunity, and I've written I think 10 or 11 letters to the Chancellor of the Duchy of Lancaster in recent weeks, making very clear what our position is in relation to those negotiations. But, actually, those should be the topic of discussions at the JMC(EN), which, if it lived up to its terms of reference, would enable that kind of shared participation to take place—it hasn't yet done that.
