The Electoral Commission would be the obvious body to do this work, because it has done the original study and is very familiar with it. I do not think that it would take long at all, given a decent computer; it is a perfectly simple mathematical formula. It would generate a notional electorate for each constituency. I agree with the noble Lord-I was going to say this later-that there are practical matters to be sorted out later about whether the proposal is workable. That is why I said that the amendment is exploratory and is not necessarily the finished article.
