A powerful committee of MPs will later issue its verdict on the phone-hacking scandal at the News Of The World and how it was handled by senior executives.
The Culture, Media and Sport select committee is also expected to rule on whether Parliament was misled over who knew what about the scandal at the former Sunday tabloid.
The committee heard evidence from Rupert Murdoch, his son James and Rebekah Brooks at the height of the furore last summer.
Former NOTW editor Colin Myler, ex-legal manager Tom Croneand Les Hinton, who worked for Rupert Murdoch for more than 50 years, were also grilled during the investigation.
The report's publication comes days after Rupert and James Murdoch both appeared before the Leveson Inquiry to face further questions about practices within News Corporation.
And it comes just 24 hours after David Cameron was summoned to the Commons to account for the lack of an investigation into the row over Jeremy Hunt and News Corp's takeover bid for BSkyB, which owns Sky News.
In a rowdy session, the Prime Minister again insisted there is currently no need to investigate emails sent by a ministerial aide for the Culture Secretary to News Corp about the bid.
The Culture, Media and Sport select committee first investigated hacking claims in 2009.
It reopened its inquiry last July after it emerged murdered schoolgirl Milly Dowler's phone had been hacked.
James Murdoch was recalled for a second evidence session last November after Mr Myler and Mr Crone told MPs they had warned him in June 2008 about the significance of a note - which became known as the "For Neville" email - revealing hacking was widespread.
Mr Murdoch rejected their version of events and told the committee he had not learned until last year that the practice went beyond a single "rogue reporter".
Rupert Murdoch told the committee that his appearance in Parliament was the most humble day of his life.
At the Leveson Inquiry, he claimed there had been a "cover-up" at the paper.
The committee will present its report to Parliament, which is likely to hold a debate on its findings, and the Government then has 60 days to respond.
