The enquiry into MG Rover's collapse has finally been completed after three years of investigation, at a total cost to the tax payer of more than £16 million.
However, the findings have not yet been made public.
The enquiry looked into what happened between MG Rover's acquisition by Phoenix Ventures in 2000 and the firm going into administration in 2005, with the loss of 6000 jobs.
Birmingham Northfield MP Richard Burden has reported that he has been told by business minister Ian Lucas that the inspectors delivered their report on 11 June. The report is now with the business secretary Lord Mandelson.
When Rover collapsed, the government announced a £150m support package for those losing their jobs and for the estimated 12,500 people in affected subsidiary firms.
Burden told the BBC: "Like everybody else in the area I have found it incredibly frustrating that we have had to wait so long for this report.
