Fresh questions overshadow launch of Sun on Sunday News International faces fresh questions. Rupert Murdoch's News International will face fresh questions over allegations of bribes at the Sun and hacking at the now-closed News of the World just one day after the publisher launches the Sun on Sunday. According to court documents filed by victims of hacking, a "senior executive" at the company repeatedly tried to cover up evidence of phone hacking by demanding the deletions of emails in 2010. Keenly awaited testimony from the Metropolitan police due on Monday is likely to provide further information about the extent of alleged corrupt payments at the tabloid. Dozens of new phone hacking cases are also expected to emerge on the same day in the high court as the newspaper publisher concludes a six-figure hacking settlement in what had become an acrimonious legal battle with the classical singer Charlotte Church. Detective Assistant Commissioner Sue Akers is due to give evidence to the Leveson inquiry - which is restarting on Monday - to focus on the relationships between the press and police. It will be the first time Akers has spoken in public since five more Sun journalists were arrested by the police on suspicion of making corrupt payments to police officers and other public officials. The latest arrests prompted a crisis at the tabloid and had the unlikely outcome of persuading Murdoch to return to the UK and launch the Sunday edition of the tabloid. A total of 10 current and former Sun journalists have so far been arrested. Elsewhere in the high court, Church is due to attend while a statement of apology is read out in open court. But while the Welsh singer's case is settled, a different hearing before Mr Justice Vos is expected to hear that dozens of new hacking cases will be launched, with some indicating that as many as 150 claimants are in the pipeline. Meanwhile, according to the legal documents released by the high court, an unnamed senior executive at News International pressed for the publisher to delete archives of journalist emails as the number of phone hacking lawsuits began to rise. The documents also say that an unnamed senior executive asked an employee of News International to remove seven boxes of their own records from the company's storage facility in July 2011. The mounting pressure could not come at a worse time for Murdoch, who this weekend is gambling on the launch of the Sun's Sunday edition, seven months after the News of the World closed. The competing Mirror, People and Star titles decided on Friday to fight back by slashing their cover price to match the Sun's 50p discounted price point. Murdoch, meanwhile, took to Twitter, to say: "The Sun: great speculation, sweeps, etc on Sunday's sale. I will be very happy at anything substantially over two million! The generic court documents filed by victims of hacking, based on evidence collected from more than 50 civil lawsuits and released for the first time this week, suggest that the deletion policy was widely discussed and to some degree carried out. News International allegedly produced an email deletion policy in November 2009 whose aim was to "eliminate in a consistent manner" emails "that could be unhelpful in the context of future litigation." According to these documents, the unnamed senior executive wrote on 29 July 2010: "How come we still haven't done the email deletion policy discussed and approved six months ago?" at the point when the publisher was on the receiving end of phone hacking claims from Sky Andrew, football agent to Sol Campbell, and Andy Gray, the presenter. A further email dated August 4 2010 was quoted as saying: "Everyone needs to know that anything before January 2010 will not be kept." On October 7 2010, this was allegedly followed by an email asking how "are we doing with the ... email deletion policy," sent to a senior employee at the News of the World publisher, News Group Newspapers, was forwarded to a member of the company's IT team. The employee wrote a covering note, saying: "Should I go and see [them] now and get fired - would be a shame for you to go so soon ?!!!." The publisher of the now-closed News of the World also destroyed "all computers used by its journalists," according to the claimants, in about October 2010 - including one machine of a reporter named specifically in actor Sienna Miller's phone hacking claim, while in January 2011 all emails on its archive system up to 31 September 2007 were deleted, according to a witness statement from NI's recently appointed chief information officer. Phone-hacking civil suits followed, with a case brought by Max Clifford being settled privately in early 2010 following a Mayfair lunch between the PR veteran and News International's then chief executive, Rebekah Brooks. Specific requests for deletions allegedly came after the company received a letter dated 6 September 2010 from Miller's legal team that demanded that all relevant documents and emails be preserved by News Group Newspapers. The latest court documents allege that three days later, on 9 September, an employee in the technology department wrote: "If the deletion need [sic] to wait until tomorrow, then that is fine. Last month, the high court heard that News Group Newspapers had agreed - for the purposes of resolving hacking settlements - that "senior employees and directors" knew about phone hacking and sought to conceal it by "destroying evidence of wrongdoing, which evidence included a very substantial number of emails" and the computers of three journalists which had been used when Mulcaire was employed under contract by the News of the World.
