it is beyond reasonable argument that sections of the Metropolitan Police Service failed to act properly in this matter, through corruption and negligence."

Despite a series of investigations over the private detective's murder, in 1987, nobody has been brought to justice.

His family have claimed that he was close to revealing police corruption when he was killed.

Last May, Home Secretary Theresa May launched an independent inquiry to look at any police involvement in the murder and the possible role played by corruption in protecting those who killed him.

In its request to the mayor to approve this payment, the Greater London Authority said: "Irrespective of the outcome of the Panel’s inquiry, it is beyond reasonable argument that sections of the Metropolitan Police Service failed to act properly in this matter, through corruption and negligence."

It also said: "This payment is exceptional and recognises the efforts of the family, the particular nature of their campaign, the length of time over which they are campaigning, and the very real public benefit of maintaining this case in the public eye."
