News Corporation chairman Rupert Murdoch has again apologised for phone-hacking at the News of the World newspaper in Britain and says he failed over the matter.
Questioned for a second day in London at the Leveson inquiry into press ethics, Mr Murdoch said he and other senior executives were shielded from the extent of illegal activity at the newspaper.
He said somebody organised a cover-up and he regretted that.
Mr Murdoch, 81, said senior executives were misinformed about the extent of the phone hacking, but he should have paid more attention.
The News of the World was closed amid a scandal after it emerged that a murdered schoolgirl's phone had been hacked.
At the end of seven hours of evidence to the inquiry, Mr Murdoch urged Lord Justice Leveson not to over-regulate the press.
''I think you have a danger of putting regulations in place which will mean there will be no press in 10 years to regulate.'' he said.
''And I honestly believe that newspapers and all they mean, mistakes and qualities, are a huge benefit to society.''
