Media baron Rupert Murdoch is in London to face a burgeoning telephone hacking scandal that forced the closure of his News Corporation's flagship tabloid, the News of the World.

The 80-year-old Murdoch arrived at his London offices Sunday with a copy of the 168-year-old newspaper's last edition in hand.

Past and recent officials at the newspaper, including British Prime Minister David Cameron's former spokesman, Andy Coulson, are at the heart of allegations that reporters paid police for information, and hacked into the voicemails of young murder victims and the grieving families of soldiers killed in Afghanistan.

Police on Friday arrested Coulson, who resigned his government post early this year, and former editor Clive Goodman, who once managed the newspaper's coverage of the royal family. Coulson quit the newspaper in 2007, after one of his reporters and an investigator were convicted of hacking into the phones of aides to the royal family.

Police on Friday also raided another tabloid, the Daily Star, on suspicion of phone hacking.

Prime Minister Cameron has promised a full public inquiry into the scandal and has pledged to appoint an independent panel to draft new regulations for British news organizations. He also said British politicians have long turned a “blind eye” to bad media practices in order to win the endorsements of influential newspapers.
