Summary Box: UK regulator investigating Sky News

The Associated Press

THE PROBE: British officials say they are investigating email hacking by Rupert Murdoch's Sky News. Minutes later, the channel's head of news acknowledged that his station had broken the law.

THE ISSUES: The U.K. broadcast regulator plans to center its investigation on "fairness and privacy issues" stemming from Sky News' admission that it had authorized journalists to hack into email accounts to score exclusives.

THE BIG PICTURE: The revelation has spread Britain's phone hacking scandal to a new branch of Murdoch's media empire and dealt a further blow to his hope of winning full control of British Sky Broadcasting.
