The Met Police is being sued for race discrimination by a senior black officer who has alleged his career was held back because of the racist views of his colleagues.
Superintendent Paul Wilson claimed he was sidelined after he made a report into racism in the police that alleged poor treatment of black and ethnic minority officers.
Wilson, who has been on the force for 31 years, said his investigation was suppressed by senior colleagues.
Wilson’s claim will be heard by an employment tribunal in West Croydon this week, the Daily Telegraph has reported.
The superintendent has been an outspoken advocate of equality and is a founding member and former chairman of the Metropolitan Black Police Association.
Wilson has previously called for police to “name and shame” senior officers who are not prepared to act against racism.
A Met spokesman said: “Superintendent Paul Wilson is bringing an employment tribunal claim against the Met citing race discrimination over the handling of his professional development review for the reporting period 2008-09.
“The Met does not recognise the position superintendent Wilson describes and will robustly defend the claim.”
