The president of the British Association of Chief Police Officers has accused News Corp Chairman Rupert Murdoch of showing "a complete denial of any responsibility" for the telephone hacking activities that forced the shutdown of the 168-year-old tabloid News of the World , Murdoch's most profitable newspaper. Orde, who is being tipped to succeed Paul Stephenson as London's top police official, lambasted Murdoch during two interviews over the weekend. He praised Stephenson, who quit last week, for "standing up" and being accountable for his decisions. "It is a stark contrast to the way in which others have sought to meet their responsibilities." Meanwhile, News International has sent notices to staff of its other London publications ordering them not to delete emails and documents that could be regarded as relevant to the current police and parliamentary investigations into the phone-hacking scandal.
