What is the main idea of the news item? [originaltext] (8)One of the world’s

(8)One of the world’s biggest media groups, News International, is apologizing and offering compensation for the actions of one of its newspapers which hacked into the mobile phones of celebrities over a sustained period.
    These are sensational admissions that are likely to cost the newspaper tens of millions of dollars in compensation payments.(9)The list of claimants includes film stars, like the actress Sienna Miller and public figures such as the politician and former Culture Minister Tessa Jowell. A reporter and a private investigator at News of the World had already been jailed in 2007 for hacking into voicemail messages left on mobile phones. But the News of the World had always claimed that instances of hacking were isolated and that the pair acted without the knowledge of senior editors. It now appears the problem went far further.
