Is the hon. Member for Birmingham, Selly Oak (Dr. Jones) not absolutely right? Is there not plentiful evidence from audit studies over many years showing that the public sector is very poor at commissioning and managing capital projects, whether for central Government, the NHS or local government? Are there not plenty of studies, which the hon. Gentleman has chosen not to quote, questioning the cost-effectiveness of those PFI schemes that have proceeded? Is it not time that we had a clear comparator that showed us whether we are getting value for money in the expenditure of public funds?
