It might be helpful to recollect that when the referendum on devolution took place in Scotland, there were two questions. One was on the principle of devolution but the other was whether a devolved Assembly, as it was called in those days, should have tax-varying powers. That was separated out in the case of Wales but in Scotland, where I was, we had a vote on both at the same time. On exactly the point that the noble Lord was making, we had the democratic decision with a substantial majority that the Assembly, as it was then called, should have tax-varying powers. We got it all achieved in one.
