ITV News has calculated that the Daily Mail paid Steve Whittamore £143,159 for potentially illegal information and made 1,728 requests.
According to what we've seen in the books the next biggest spenders were the Daily Mirror who spent more than £92,000 on potentially illegal information and made 984 requests.
Close behind the Mirror is their stable-mate the People, spending more than £76 000, requesting 1,016 potentially illegal searches.
A full break-down of what each national newspaper paid Whittamore for data can be found here.
Alec Owens, who led the investigation for the Information Commissioner's Office, told ITV News that payments to private investigator Steve Whittamore were happening on a “massive scale” but claimed only about 1% of victims have been informed.
Charlotte Church told ITV News the amount of information held on her by some national newspapers during her teens was "all encompassing of everybody I'd ever known". Watch more from the singer here.
A spokesperson for the Information Commissioner's Office said: "We have provided the Leveson Inquiry with extensive oral and written evidence relating to Operation Motorman. We now await the Inquiry’s outcome, and will respond appropriately to any relevant recommendations.
“While we had reason to believe that some of the material could only have been obtained via unlawful means, the press are able to claim a public interest defence. This could explain an apparent discrepancy in figures."
