Speaking during a Commons sitting on the past years' PAC reports, David Davis said the government's failure to address the crucial issue of auditing performance measurement in Whitehall was 'beyond comprehension'.
Under resource accounting and budgeting, whereby the government introduces commercial accounting practices, individual departments must prepare statements of performance.
But despite this, the government has not yet decided whether they will be individually audited.
The Commons Treasury Committee has already reported that performance measurement should be audited and that the National Audit Office would be the best body to do it.
'It is vital that the public should have absolute confidence on government information,' Davis told MPs.
The best value regime in local government means councils are subject to similar controls. 'Yet in central government the same approach is deemed inappropriate,' Davis said.
