The acting director-general of the BBC has vowed to get a grip at the corporation following the resignation of the director-general over a broadcast on child abuse allegations.
Tim Davie says he has set up a clear line of command in news.
He was appointed to the role on Saturday after the previous director-general left with a year's salary of £450,000, after eight weeks in the post.
The director and deputy director of news have also been asked to step aside pending an internal review into the way claims about Sir Jimmy Savile were handled.
In a televised interview, Mr Davie said:
"If the public are going to get journalism they trust from the BBC I have to be, as director general, very clear on who is running the news operation and ensuring that journalism we put out passes muster.
"The first decision I have made is to get a grip of that, take action and build trust by putting a clear line of command in.
The BBC is also looking into the culture and practices at the corporation during Savile's career and its handling of past sexual harassment claims.
