Media tycoon Rupert Murdoch could soon lose his business empire after a British parliamentary committee released a report Tuesday saying he no longer fit to run News Corp.

Murdoch and his son, James, are being held responsible for Britain's tabloid phone hacking scandal involving News of the World.

The scandal involved the hacking of voice mail messages of celebrities and victims of crime, including murdered schoolgirl Milly Dowler.

Lawmakers accused the Murdochs of managing a corporate culture that sought "to cover up rather than seek out wrongdoing."

The elder Murdoch has insisted his staff left him in the dark and that he played no part in the cover-up of his company's wrongdoing.

But legislators dismissed his claim, saying that Murdoch and his son both exhibited willful blindness.

"As the head of a journalistic enterprise, we are astonished that James Murdoch did not seek more information," legislators wrote.
