It's no longer just the News of the World, but possibly also Murdoch's UK centerpiece The Times and The Sunday Times. The Guardian:
Other titles in Rupert Murdoch's media empire, including the Sunday Times, are being investigated for allegedly hacking into mobile phones belonging to well-known people, according to Lord Prescott.
The former deputy prime minister used parliamentary privilege to claim in the House of Lords: "The investigation into phone hacking has been extended now to the Sunday Times."
Scotland Yard announced a fresh inquiry into allegations of widespread phone hacking at the Murdoch-owned News of the World in January. The Met also told Prescott there was evidence his phone may have been targeted by Glenn Mulcaire, a private investigator who was employed by the paper.
