The BBC's director of news, Helen Boaden, and her deputy have "stepped aside" pending the outcome of an internal review.
The move by Ms Boaden and Steve Mitchell comes after director general George Entwistle quit on Saturday.
The BBC said it was not commenting yet, but there will be an announcement within hours.
Mr Entwistle resigned after a Newsnight report led to a former Tory treasurer being wrongly accused of child abuse.
He had also commissioned two inquiries into an earlier Newsnight decision not to broadcast a report on allegations of abuse by former BBC presenter Jimmy Savile.
Ms Boaden was director of BBC News and Mr Entwistle was director of BBC Vision at the time of the decision not to broadcast the Savile allegations late last year.
One of the inquiries is being headed by former Sky News head Nick Pollard. He will look into why the Newsnight investigation was shelved.
Ms Boaden and Mr Mitchell have been asked to surrender all their responsibilities as head and deputy head of BBC News, pending the results of the Pollard inquiry.
