The chief executive of Rupert Murdoch’s British newspaper division has resigned in the wake of the phone-hacking scandal engulfing Murdoch’s media empire. Rebekah Brooks was editor at the News of the World tabloid when it hacked into the voicemail of murder victims and their survivors. As one of Murdoch’s top confidantes, she had faced intense calls to step down when the scandal broke, but Murdoch and his son James had defended her tenure. Brooks says she will now devote her full attention to cooperating with a police probe and a British parliamentary inquiry. Her resignation comes one day after another former News of the World executive, Neil Wallis, was arrested, becoming at least the ninth person detained in the scandal so far.
