This gets worse.
A police watchdog has ordered an inquiry into claims that a senior Scotland Yard officer advised defence lawyers on how to undermine a case being prosecuted by his own force. 
Commander Ali Dizaei is alleged to have acted as a consultant to the lawyer at the heart of the Yard race row in a case involving a woman accused of causing death by dangerous driving. 
Today the Metropolitan Police Authority announced that it had called in an outside force to investigate the allegations involving Mr Dizaei, who is president of the National Black Police Association.
Mr Dizaei, who has not been suspended, will be issued with a Regulation Nine notice giving him warning that he is under official investigation.
The Daily Mail today reports that Dr Mireskandari allegedly used the police officer as a consultant to point out flaws in a death by dangerous driving prosecution being brought by the Met against one of the lawyer's clients.
The 47-year-old has publicly vowed to destroy Sir Ian's 'golden circle' of white officers which, he claims, resulted in Ghaffur being sidelined because of his colour.
Today we can reveal that in a tape recorded conversation Mireskandari spelt out Dizaei's role in the defence case.
Dr Mireskandari, 47, co-founder of the solicitors Dean and Dean, is said to have held a case conference on the hit and run case in his offices last year and announced that Mr Dizaei was coming into the office to give advice.
However, because of concern among some of those present, Mr Dizaei was not invited to join the conference but one of the team was told to go to 'hear what he had to say'. It is alleged that the Commander then gave advice on weaknesses in the Met case and how they could be exploited.
An MPA spokesman said: 'We can confirm that Commander Dizaei is currently being investigated by the MPA for a matter of alleged misconduct.'
Last night it also emerged last year the woman defendant in the death by dangerous driving case was a guest at Dizaei's third wedding reception at a West London restaurant, while she was on bail.
The revelation that Dizaei tried to undermine a case will lead to calls for him to be investigated over his links to the lawyer. We can also reveal today that Keith Vaz, a former Labour minister and now chairman of the home affairs select committee, is a personal friend of the conman.
Mr Dizaei, 45, issued a statement saying he had 'no recollection' of meeting the defendant.
He said: I am president of the National Black Police Association and in that capacity I speak to many people.'
Mr Vaz has been an enthusiastic supporter of the lawyer's attempts to force an investigation into alleged racism by the solicitors' watchdog.
Last year Mr Vaz wrote to the SRA complaining on behalf of Mireskandari about the watchdog's alleged 'prejudicial and discriminatory conduct' against his firm.
Last night Mr Vaz refused to comment.
The Solicitors Regulation Authority is investigating Mireskandari. He has responded with a £10million lawsuit against the SRA. Our revelations have already sparked calls for Mireskandari to be suspended pending the outcome of the probe.
