Rupert Murdoch has been recalled to give evidence to MPs after a recording emerged of him apparently venting his anger about police investigations into phone-hacking and payments to officials.

The Commons Culture Media and Sport Committee will ask the mogul to appear before it again to discuss his comments in the autumn. Scotland Yard said it will "fully assess" the recording of his comments in a meeting with News International journalists.

Critics said the tape showed Mr Murdoch's real attitude to the crises that have engulfed his empire, in contrast to his contrition when giving evidence to the committee two years ago.

The Hacked Off campaign group has demanded his recall and suggested he may have committed a contempt of parliament.

The News Corp boss is heard saying the treatment of arrested journalists was a "disgrace" and suggesting he regretted the extent to which the company had co-operated with the investigation.

The audio, broadcast by Channel 4 News, was said to have been made in March during a meeting with journalists from The Sun at his British newspapers' headquarters in Wapping, east London.

Mr Murdoch is heard railing at the way the police behaved. "It's a disgrace. Here we are, two years later, and the cops are totally incompetent," he said. "The idea that the cops then started coming after you, kick you out of bed, and your families, at six in the morning, is unbelievable.

"But why are the police behaving in this way? It's the biggest inquiry ever, over next to nothing... They're going to put all newspapers out of business."

When asked why so much material had been handed over to police by News Corp's management and standards committee, Mr Murdoch indicated he believed they had gone too far.
