On the role of politicians, Lord Justice Leveson says they "have had or developed too close a relationship with the press in a way which has not been in the public interest".
But he clears Jeremy Hunt - the then Culture Secretary, in the way he acted over News Corp's bid to buy BSkyB.
"Mr Hunt immediately put in place robust systems to ensure the remaining stages of the bid would be handled with fairness, impartiality and transparency, all in line with his quasi-judicial obligations.
"In every respect bar one, the bid was commendably handled."
He does suggest Mr Hunt's special adviser, who resigned, should not have been put in the position he was, given his closeness to the News Corp's lobbyist Frederic Michel.
Lord Justice Leveson says a genuinely independent and effective system of self-regulation is needed.

Nick Clegg sources say it is inevitable there will be differences between his response to the Leveson report and the Prime Minister's.
