London, Jan 15 (Agencies): Prosecutors said on Friday that a politically sensitive investigation into phone hacking charges against one of Britain's best-selling tabloid newspapers would be reopened.

Chief prosecutor Keir Starmer said that a "comprehensive assessment" of all evidence would be held to see whether new charges should be brought in the case involving The News of The World, owned by Rupert Murdoch's media company.

"The purpose of this assessment is to ascertain whether there is any material which could now form evidence in any future criminal prosecution relating to phone hacking," prosecutors said in a statement.

The criminal inquiry will focus new attention on the tabloid's sophisticated phone-tapping operation, which included hacking into cell phones used by senior aides of the royal family in order to listen to voicemail messages.

Actress Sienna Miller and other celebrities have also accused the paper of illegal hacking and harassment, leading to the recent resignation of Ian Edmondson, a top executive.

The News of The World has been at the centre of the scandal since a reporter and a private investigator employed by the title were caught illegally eavesdropping on the phones of the British royal family's entourage.
