Gerry McCann, father of missing Madeleine, has urged the Prime Minister to "do the right thing" and implement Lord Justice Leveson's recommendations in full.
ITV News correspondent Paul Davies reports:
A man who won libel damages after his arrest over the murder of a woman has written to MPs asking them to back Leveson's recommendations.
About 2,000 editors will sign up to a new independent press watchdog, the chairman of the Press Complaints Commission has said.
The Prime Minister has taken a political gamble by holding differing views to the victims, the Leveson inquiry and a majority of MPs.
