The BBC has called on Nick Pollard, a former head of Sky News, to carry out an independent inquiry into the corporation’s decision last year to axe a Newsnight investigation into sexual abuse by Savile.
The Kreab team is being led by partner James Benjamin.
PRWeek can also reveal BBC comms director Paul Mylrea and head of press and media relations Julian Payne have been asked to give evidence.
Before his resignation on Saturday, director-general George Entwistle announced last month that the BBC was launching the inquiry.
Following Entwistle’s departure, the BBC's director of News Helen Boaden and her deputy Stephen Mitchell have also announced they will ‘step aside’ from their roles, pending the results of the inquiry.
The BBC has also begun disciplinary measures against a number of those involved in the decision to run the Newsnight report on care homes in north Wales.
