I am on the same page as the noble Lord, Lord Purvis. Why is it so complicated? The joint ministerial committee system has, as he said, worked well for more than 20 years. It provides an opportunity for those who are required to be present around the table to sit down, discuss and arrive at conclusions. In a debate on an earlier Bill, the noble and learned Lord, Lord Mackay of Clashfern, suggested a way of developing that into a formal
structure within which there would be appointed chairs or elected chairs and rotating responsibilities. We seemed to be heading down that route, but now we are talking about this rather curious IGMF, which I had not heard of before. It is nice to know that it does indeed exist and may be working on EU matters. But I have always understood the relationship around EU matters as being—as the noble and learned Lord, Lord Mackay, picked up rather cleverly—around a settled set of responsibilities, where there is not the problem of geography meeting functionalism. That is the problem here, because as soon as we have a situation where the responsibility is devolved because it is not reserved, and there is a need to arbitrate and barter out the various competing interests across the nations of the United Kingdom, there has to be some formal structure. I do not think a forum provides that.
