Their own website: http://hackinginquiry.org/Hacked Off was founded to campaign for a public inquiry into illegal information-gathering by the press and into related matters including the conduct of the police, politicians and mobile phone companies. Only a full public inquiry, we argued, could put the truth of the hacking scandal before the public and ensure that necessary lessons were learned. The Milly Dowler revelations on 4 July convinced the public and the political world of the need for such an inquiry, and the campaign is now focused on monitoring the Leveson Inquiry and pushign [sic] for press reform.
