The Telegraph reported yesterday that both James and Rupert Murdoch are to be questioned under oath in the High Court as part of the Lord Leveson inquiry into phone hacking.

According to the paper’s report Lord Leveson is also “keen” for the inquiry to be broadcast live. A Cabinet Office spokesman declined to comment on whether the Murdochs will be questioned, but told Journalism.co.uk live coverage of the inquiry is being looked into.  The closing date for submissions to the inquiry is tomorrow, with reportedly “dozens of letters” already having been sent to potential witnesses to ask for their input.

The Murdochs, as well as Andy Coulson and Rebekah Brooks, both former editors of the News of the World, are likely to be called.

David Cameron and other senior politicians are also likely to be questioned over their links to News International, the parent company of the News of the World.

Today Reuters also reported that lawyers for News International are carrying out “a broad inquiry into reporting practices at all of the company’s UK newspapers”.

Citing sources who have been briefed about the inquiry Reuters reports that lawyers for law firm Linklaters will be “looking for anything that US government investigators might be able to construe as evidence the company violated American law”.

In addition to conducting personal interviews with selected journalists, lawyers will also be looking at email and financial records, said this source.

A News International spokesman confirmed that a review of journalistic standards is underway at News International, which Linklaters is assisting with.

“This is part of a process that started a number of weeks ago and is under the ultimate control of the News Corp board through the independent director Viet Dinh, Joel Klein and the Management and Standards Committee”.
