I thank my hon. Friend for his answer, which seems to indicate progress with honouring a commitment given to the Treasury Committee last June. As my hon. Friend will be aware, both the Treasury Committee and the Public Accounts Committee have expressed doubts about the reliability of the construction of the public sector comparator, as those responsible do not see public finance as a serious alternative. Does he agree that the best way of dealing with that problem is for the Government to announce that public finance will be available for worthwhile capital projects, such as the new hospital in south Birmingham, if it can be shown that that is a better way than private finance of giving value for money to the taxpayer?
