Deloitte and one of its partners failed to properly consider conflicts arising from advising MG Rover Group and its Phoenix Four directors who bought the carmaker before it collapsed, Britain's accounting policeman said on Thursday.

Deloitte said it disagreed with the complaint which it expected to be dismissed at a public hearing.

MG Rover was put into administration in 2005 with debts of 1.4 billion pounds and the loss of 6,000 jobs. Four of its directors had set up Phoenix to buy lossmaking carmaker for a token 10 pounds five years earlier.

There was public anger when it emerged the four had paid themselves 40 million pounds in salaries and pensions before MG Rover collapsed.

The four faced no criminal charges but were disqualified from being directors of any company for up to six years.

The Accountancy and Actuarial Discipline Board (AADB) last year opened a probe into Deloitte, which audited MG Rover, and Maghsoud Einollahi, who worked in the auditor's corporate finance department which advised MG Rover group companies.

The AADB said it had filed a formal complaint alleging that the conduct of Deloitte & Touche and of Mr Einollahi fell short of the standards reasonably to be expected regarding objectivity and due care.

The complaint will be heard before an independent tribunal and, if upheld, Deloitte and Maghsoud could face unlimited fines.

The AADB said Deloitte and Einollahi had acted as corporate finance advisors to various companies involved with MG Rover and the Phoenix Four. During this time Deloitte was also auditor for MG Rover.

DIFFERENT INTERESTS

The regulator said Deloitte and Einollahi failed to consider adequately the public interest and the potential for there to be different commercial interests between the Phoenix Four, MG Rover, associated companies and shareholders.

They also failed to consider properly the conflicts of interest and self-interest threat while advising the Phoenix Four whiles maintaining client relationships with MG Rover, the AADB said.

The AADB is not alleging misconduct in relation to the audit work performed by Deloitte for the MG Rover Group, the regulator said.

Deloitte said in a statement it was disappointed that the AADB had taken the view that limited aspects of its advisory work relating to two transactions in 2001-2002 fell short of acceptable standards.

We do not agree with the AADB and are confident that when all the evidence is considered, the tribunal will conclude that there is no justification for criticism of either Deloitte or our former partner Mr Einollahi, Deloitte said.

We are pleased that the AADB confirmed that there are no grounds for complaint in relation to Deloitte's audit work, Deloitte added.

Regulators are cracking down on potential conflicts of interest in the auditing sector, where policymakers suspect that auditing work is used to open the door to lucrative advisory services for the same customer.

The European Union has proposed a draft law that would in some cases force the Big Four -- Deloitte, Ernst & Young , KPMG and PwC
-- to separate their auditing and advisory services to avoid conflicts of interest and make it easier for smaller rivals to compete.
