MPs are demanding to know why there is still no end in sight to a long-running, £11 million inquiry into the collapse of MG Rover.
The Commons Business, Enterprise and Regulatory Reform Committee is considering launching a probe into why accountants BDO Stoy Hayward are taking so long.
There are also concerns about the cost, which recently passed £11.1 million, including about £125,000 spent by inspectors on hotels, food and drink.
Committee chairman Peter Luff has now written to Business Secretary John Hutton urging him to set out a timeframe for the inquiry’s completion. The Conservative Mid-Worcestershire MP said: "The Government is declining to comment on why it’s taking so long and it’s not good enough.
"We think it’s time that everyone involved realises there is a degree of urgency here. People paid a heavy price for what happened to MG Rover and it won’t do for this just to go on and on."
The independent inquiry was set up in June 2005 after the Longbridge plant, in the West Midlands, closed with the loss of 6,000 jobs.
Frustrations have grown as ministers have repeatedly declined to say when the inquiry might be completed. It was set up under the Companies Act nearly three years ago by then trade and industry secretary Alan Johnson.
Mr Johnson said at the time an investigation covering the two years leading up to the collapse was in the public interest. He added: "I have asked (the inspectors) to report to me as quickly as possible."
In his letter, Mr Luff said: "While the committee does not wish to prejudice the inquiry in any way, we are becoming increasingly concerned about the lack of clarity about when the inquiry is expected to end, and about the reports of the high costs involved."
The committee has requested a "broad indication" of the likely timeframe and a new estimate of the costs.
Mr Luff added: "Although we are concerned about the length of time this inquiry is taking, we also have concerns about whether this is an isolated problem, or indicates broader problem with the Companies Act itself.
"To help us judge this, the committee would also like information about the average time spent on a Companies Act inquiry, and the range of costs incurred by such inquiries."
A Department for Business spokesman said: "It is crucial that the independent investigators are able to conduct an accurate, thorough and fair inspection that provides full answers to what happened when MG Rover collapsed in 2005.
"To place an arbitrary deadline on the report could put this at risk. We meet regularly with the inspectors to ensure the momentum of the investigation is maintained and that the costs are contained as far as possible.
"We are confident that the inspectors are intent on completing the investigation as quickly as possible."
