Andy Coulson, British Prime Minister David Cameron’s communications head, has resigned, saying that the phone-hacking scandal surrounding him has impeded his ability to do the job. He’s become the story. “When the spokesman needs a spokesman, it’s time to move on,” Coulson said. Observers say that Coulson had no option but to quit. Waves of conspiracy theory and innuendo have been lapping ever closer to him. He resigned in 2007 as editor of the News Of the World tabloid because of the scandal. Last month Coulson swore under oath in court that he never knew anything about the illegal phone-hacking even though his newspaper’s royals editor Clive Goodman was jailed for conspiracy to access phone messages and private eye Glenn Mulcaire was jailed for 6 months on the same charge. Earlier this month the News of the World suspended its news editor Ian Edmondson, a key Coulson lieutenant, over hacking into actress Sienna Miller’s phone. Today’s news means that Coulson has resigned twice for something he didn’t know anything about. News International has always maintained that the reporters involved were acting on their own. Rupert Murdoch said in a speech last year that News Corp would hunt out any wrongdoing of its staff.
