A long-awaited report on the demise of MG Rover will raise questions over the right of the so-called Phoenix Four to be company directors, according to Lord Mandelson.
The report by independent inspectors, which took four years and cost £16 million of tax payer's money, will be published on 11 September after the Serious Fraud Office ruled out a criminal investigation into the affair yesterday.
The government has been accused of trying to delay the report after claims that it will show how it spent £6m trying to prop up the company to protect marginal constituencies around Birmingham in the run-up to the 2005 election.
MG Rover collapsed in April 2005 with the loss of more than 6000 jobs after the group of businessmen, now known as the Phoenix Four, bought the car maker from BMW for £10 in May 2000.
The four executives in charge - John Towers, Nick Stephenson, Peter Beale and John Edwards - came in for criticism when it was revealed they had taken out an estimated £40 million in pay and pensions in the five years they controlled the firm.
