The extent of the defunct Sunday paper's meddling in the Dowler inquiry raises new questions about how far up the executive ladder at News International knowledge of phone hacking had spread at this early stage, and why Surrey police decided not to follow up evidence that the NOTW had illegally obtained information relevant to one of the most high-profile inquiries in its history.
The failure to pursue the Sunday tabloid meant phone hacking by its journalists continued for a further four years until Scotland Yard arrested private investigator Glenn Mulcaire and the NOTW royal editor, Clive Goodman, in August 2006.
Both were later jailed.
Mark Lewis, the Dowler family's lawyer, said: "Questions have to be asked as to whether Surrey police were more concerned with selling papers than solving crimes.
"What was it with them that, when the public dialled 999, the police dialledNOTW?"
The Independent has established that, in April 2002 as police followed multiple leads, the NOTW approached the Surrey force and arranged two meetings during which it was made clear the paper had information that could only have come from messages on Milly's phone.
Two of the force's most senior detectives were at the meetings.
