Hacking trial: 'I'm extremely sorry', says PM Cameron

David Cameron says he is "extremely sorry" that he employed Andy Coulson as his director of communications.

The former News of the World editor has been found guilty of conspiracy to hack phones.

Ex-News International chief executive Rebekah Brooks was cleared of all charges in the phone-hacking trial.

Coulson and Mrs Brooks were among seven defendants on trial at the Old Bailey.
