Lord Justice Leveson and Prime Minister David Cameron have been called to give evidence to a parliamentary committee report on press regulation, it has emerged.
The House of Commons Culture, Media and Sports Committee has launched a new inquiry into press regulation. It is hoped that the Appeal Court judge - who published his report on the issue last week - and the PM will be witnesses.
At a private meeting of the committee last week, it was agreed that invitations would be sent to Mr Cameron, Lord Justice Leveson, and the Press Complaints Commission chairman Lord Hunt. Guardian editor Alan Rusbridger and representatives of the Hacked Off campaign have also been invited.
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.
