Police are investigating evidence that a News International executive may have deleted millions of emails from an internal archive in an apparent attempt to obstruct Scotland Yard's inquiry into the phone-hacking scandal. The archive is believed to have reached back to January 2005, revealing daily contact between News of the World editors, reporters and outsiders, including private investigators. A senior executive is believed to have deleted massive quantities" of the archive on two separate occasions, leaving only a fraction to be disclosed. The allegation directly contradicts NI claims that it is co-operating fully with police in order to expose its history of illegal newsgathering. Rupert Murdoch is planning to fly into London on [July 9] to confront the crisis. The scandal brought a number of arrests on [July 8], with the prime minister's former PR chief Andy Coulson held under suspicion of involvement in phone hacking. As he was released on bail, he told reporters: "There is an awful lot I would like to say, but I can't at this time." Clive Goodman, the NoW's former royal reporter, was also arrested in relation to the alleged payment of bribes to police, and subsequently bailed.
