The Deputy Met Commissioner, Craig Mackey, and the Deputy Mayor for Policing and Crime, Stephen Greenhalgh, will be questioned by members of the London Assembly on policing in the capital.
Questions are expected to focus on the detention of children in police custody, the review of victim services, hate crime, domestic extremism and the way terror suspects are dealt with.
The London Authority (GLA) police and crime panel referred a complaint to the IPCC, based on claims made by residents whose homes were facing demolition as part of the regeneration of Earls Court.
They alleged that council officials had offered priority housing to residents if they supported the regeneration.
However the IPCC said it had carried out an assessment that included consulting with police and lawyers and would not launch an investigation. It said:
"The IPCC undertook an assessment of the complaint in order to establish whether it was necessary to conduct a criminal investigation into Mr Greenhalgh.
This involved consideration of material submitted by the complainant, examination of an investigation report compiled by Hammersmith and Fulham Council's auditors,...
...consultation with officers from the Metropolitan Police Service who assessed criminal allegations made against the council officials, obtaining specialist legal advice and inquiries with one resident who was said to have information which referred directly to Mr Greenhalgh.
The IPCC has now concluded that assessment, and in the absence of any evidence to indicate that Mr Greenhalgh may have committed a criminal offence, the IPCC will not be investigating the complaint. The complaint has been referred back to the police and crime panel for its consideration."
Mr Greenhalgh, whose current role means he has the authority to appoint and sack senior officers in the capital, said when the claim was referred to the IPCC: "I am immensely proud of my record as Hammersmith and Fulham Council leader.
These baseless allegations are politically motivated. I refuse to be distracted from my important role as deputy mayor for policing and crime."
The deputy mayor for policing in London will not face investigation after he was referred to the police watchdog over claims linked to his previous job as a council leader.
Stephen Greenhalgh was referred to the Independent Police Complaints Commission (IPCC) in January over the allegations from his time at Hammersmith and Fulham Council.
He said that the claims were "baseless allegations" that were "politically motivated".Today the IPCC said:
"In the absence of any evidence to indicate that Mr Greenhalgh may have committed a criminal offence, the IPCC will not be investigating the complaint."
One of Boris Johnson's deputy mayors has been involved in a heated exchange over police numbers.
Opposition politicians cast doubt on the mayor's pledge toput an extra 1,200 police officers on the streets.
During a debate at City hall, the Deputy Mayor for Policing Stephen Greenhalgh clashed with London Assembly member Jenny Jones.
Mr Greenhalgh: "Your line of questioning indicates your lack of understanding of the figures we are presenting."
Ms Jones: "Well I think that your answer is actually a complete fudge."
Mr Greenhalgh: "You clearly don't understand the figures."
Ms Jones: "Mr Greenhalgh you're very offensive and I'd like to say that you really ought to perhaps mind your manners."
The Mayor's office has made a statement following the news that the Deputy Mayor for Policing, Stephen Greenhalgh, has been referred to the police watchdog over allegations dating back to his time as leader of Hammersmith and Fulham Council. Tonight, City Hall made this response:
Labour MP Andy Slaughter has said that the Deputy Mayor for Policing should be suspended because of fresh allegations about his previous conduct.
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.
