None, Sir. Until 1958, such a change could take place only at the request of a county borough council. Since then, the Local Government Commission for England has had powers to make proposals of this kind and has done so in five famous instances. So far, none of them has been brought into effect.
We are a long way from that. The inquiry has not yet taken place, but I gather that it should be before next spring. However, I will give the hon. Gentleman one consolation, which is that, as far as I understand it, no county borough in the history of the country has been down-graded except at its specific request.
