The paper's revelation in July that police had never properly pursued the News of the World for hacking the phone of the missing murdered girl caused a wave of public revulsion worldwide.

The ensuing uproar over police inadequacy and alleged collusion with the Murdoch media empire swept away the top officers at Scotland Yard. It also brought about the closure of the News of the World itself, the withdrawal of the Murdoch takeover bid for Sky, and the launch of a major judicial inquiry into the entire scandal.

Metropolitan police commissioner Sir Paul Stephenson and assistant commissioner John Yates both resigned. David Cameron's former PR chief Andy Coulson is among those who have subsequently been arrested for questioning, along with former News International chief executive Rebekah Brooks.

Police now intend to go before a judge at the Old Bailey in London on 23 September, in an attempt to force the handover of documents relating to the source of information for a number of articles, including the article published by Hill and Davies on 4 July disclosing "the interception of the telephone of Milly Dowler".
