The race row embroiling Scotland Yard has shows little sign of abating after a number of high-profile critics spoke out against the force and investigations into 10 cases of alleged racism involving Metropolitan Police officers continued.
Superintendent Leroy Logan, of the Black Police Association, said warnings of racism at Scotland Yard have fallen on "deaf ears" for more than a decade.
New figures showed 572 of the complaints made by staff and the public were "locally resolved" and only 42 were "substantiated".
Just two officers lost their jobs, and were required to resign rather than being dismissed, meaning they kept any pension entitlements.
The highest number of complaints was in 2008, when 500 were lodged.
