On Monday the newspaper’s editor Dominic Mohan spoke to staff in response to fears that journalists are being made scapegoats for problems within the News Corp empire.

This follows the arrest of former news editor Jamie Pyatt, for alleged illegal payments to police, on Friday.

Mohan gathered employees on Monday to tell them that he’d met with Rupert Murdoch in New York to discuss The Sun’s future. Mohan said that Murdoch was “up for the fight”.

Tom Mockridge, News Internaitonal’s chief executive, appointed in May to clean up the company’s reputation, was also there.

He told staff that The Sun had to give information to the police about staff activities, otherwise police officers would be searching the newsroom.

For over two years News International has protected The Sun and strongly denied any corrupt practice at the title.

Tomorrow James Murdoch, the News Corp deputy chief operating officer, will be questioned on his previous evidence given into the phone hacking inquiry.

He will be questioned in front of parliament about his insistence he did not know about the phone hacking scandal.

There is increasing evidence to show that Murdoch did know how widespread phone hacking was when he approved a settlement meant to hush the scandal in 2008.
