The police force that handled the Milly Dowler case said in a report this year that News of the World staff made it clear to police in 2002 that the paper had access to Milly's voice mails.
Mr Miliband said it was an insult to the family of murdered schoolgirl Milly Dowler, whose phone was allegedly hacked, that Rebekah Brooks was still News International's chief executive.
He said press treatment of those including the families of missing girl Madeleine McCann and murdered teenager Milly Dowler was "absolutely despicable", stressing he wanted a new system to prevent such things happening.
