<p>The one thing they do do now is adjust for population every year. When the Barnett formula was introduced, they only changed the population ratio once—that was when Michael Portillo was Chief Secretary to the Treasury; that's going back—until Labour came back to power. Then, Alistair Darling did introduce an annual review of population. So that one is done now, in fairness; it's the whole raft of other factors—. And again, the House of Lords select committee—I think it was Lord Moser, who used to run the Central Statistical Office, as it was in the old days, as it was called, had some ideas there. It shouldn't be beyond the wit of man broadly to agree a set of parameters that we can check every year or two what are the shifts in relative need. Just to show the inertia around this, when I gave evidence to that select committee, I was showing off a little bit, so I went back to the Goschen formula, which predates the Barnett formula. And one of the peers—I won't name him—came up to me over coffee, and gently said, 'You know, Scotland's generous treatment goes back before the Goschen formula, it goes back to the Act of Union.' He said, 'One of my ancestors negotiated it.' Because to oil the wheels of the union, if you like, they decided to give Scotland a relatively generous settlement. And it just shows the sheer almost inertia in the systems that we've still got it today.</p>
