The deputy mayor for policing in London is being investigated by the police watchdog over allegations linked to a previous job.
A spokeswoman for the Independent Police Complaints Commission (IPCC) said the body received the referral about Stephen Greenhalgh yesterday from the Greater London Authority (GLA).
She said: "This referral follows a complaint made to the GLA regarding the conduct of deputy mayor for policing Stephen Greenhalgh.
"The allegations which form the complaint relate to Mr Greenhalgh's previous role at a London local authority. The complaint is currently being considered by the IPCC."
Mr Greenhalgh's current role means he has the authority to appoint and sack senior officers in the capital.
