LONDON - Rupert Murdoch said Friday he will launch a Sunday version of his top-selling British tabloid The Sun “very soon”, as he sought to boost morale among staff left angry and hurt by a wave of arrests. The media tycoon said that despite a police investigation into claims that journalists paid police and other public officials for information, the tabloid would not suffer the same fate as its sister paper, the News of the World. Murdoch shut the News of the World, a Sunday tabloid, in July over a phone-hacking scandal, which has spawned three police probes and a government-ordered inquiry into the standards and ethics of the British press.
