I am not sure how many elderly people would find themselves in that predicament, but such circumstances ought to be dealt with in the design of a mansion tax. The hon. Gentleman will therefore see the logic of our new clause, which seeks to encourage the Chancellor to introduce proposals within six months. Let us look at the design of them, and think about those rare circumstances in which someone might be living in a £2 million property but have no means by which to pay an annual levy. I imagine that that would be quite rare—it is perhaps quite difficult to believe—but such circumstances might exist. I am convinced that the hon. Gentleman’s Liberal Democrat colleagues have thought through all those points when they drew up their carefully crafted proposals. Perhaps there are channels between the coalition parties that we are not party to, and perhaps they exchange information on these matters. I am sure that such a tax could be designed correctly, if not by the Chancellor then by the Office for Budget Responsibility, if that would be a better way of doing it.
