British sports agent Paul Stretford, who represents Manchester United soccer star Wayne Rooney, is the latest figure planning to sue Rupert Murdoch's London tabloid News of the World after learning from police that his voicemails had been hacked by a private detective working for the newspaper. Published reports in the U.K. said today (Thursday) that police had shown Stretford pages from notebooks kept by the detective, Edward Mulcaire, which included phone numbers of "friends and associates." The reports suggested that among those friends and associates was Rooney and that he, too, might join the growing list of litigants. Meanwhile, MP John Whittingdale, chairman of the House of Commons Media Select Committee, said in an interview on BBC Radio that he may launch an investigation into the relationship between Murdoch's newspapers and Scotland Yard. Several of Whittingdale's colleagues, who also claim that their phones were hacked, have previously charged that police failed to follow up on evidence that News of the World reporters routinely accessed the voice mail of politicians and celebrities. Said Whittingdale "It seems pretty extraordinary that newspapers are able to listen in to the private conversations of Downing Street, royal staff and others. I'm wanting to know why those responsible for safeguarding security weren't able to do anything about it."
