Former employees Colin Myler, editor of the now defunct News of the World and NoW legal manager Tom Crone are challenging his version of events.
Here’s what the BBC says.
Evidence on phone hacking given to MPs by News International chairman James Murdoch has been called into question by two former executives at the firm.
Mr Murdoch told the media committee he was not “aware” of an email suggesting the practice went wider than a “rogue” News of the World reporter.
Former NoW editor Colin Myler and ex-NI legal manager Tom Crone said they “did inform” him of the email.
Mr Murdoch says he “stands by his testimony”.
Meanwhile, Sun features editor Matt Nixson has been sacked from the paper in relation to claims of phone hacking while he was at the News of the World.
The management and standards committee of News Corporation, the parent company of News International, confirmed it had “terminated the contract of a member of staff in relation to his previous work”.
In April 2008, Mr Murdoch authorised the payment of an out-of-court settlement of more than £600,000 to Gordon Taylor, chief executive of the Professional Footballers’ Association, over the hacking of his phone.
Commons culture, media and sport committee chairman John Whittingdale says the committee will ask Mr Murdoch to clarify what he said on the matter as part of a written response containing additional information that he has already promised to provide.
