Private Eye editor Ian Hislop will join a series of national and regional newspaper editors giving evidence to the Leveson Inquiry next week.
The press standards inquiry will hear from Guardian editor Alan Rusbridger, Times editor James Harding and Daily Mirror editor Richard Wallace. Tom Mockridge, who took over as chief executive of News International from Rebekah Brooks last July, and Sly Bailey, chief executive of Trinity Mirror, will also appear.
Mr Hislop is likely to be asked about how Private Eye, which celebrated its 50th anniversary last year, deals with complaints given that it does not sign up to industry regulator the Press Complaints Commission.
Meanwhile, the publisher of two of the UK's most popular newspapers has asked senior judges to consider whether the inquiry into press standards should hear evidence anonymously.
Associated Newspapers, publisher of the Daily Mail and The Mail on Sunday, said it feared that its reputation could be tarred by evidence given anonymously to the Leveson Inquiry, sitting in London.
Lawyers representing Associated Newspapers challenged a ruling on the admissibility of anonymous evidence by inquiry chairman Lord Justice Leveson, at a High Court hearing in London before Lord Justice Toulson, Mr Justice Sweeney and Mrs Justice Sharp.
In a ruling on November 9, Lord Justice Leveson said he would be "prepared to receive anonymous evidence". He said the inquiry had been approached by a number of individuals, "all of whom describe themselves as journalists working for a newspaper or newspapers", who had asked to provide evidence anonymously and not to be identified to the newspaper or newspapers for which they work or had worked.
Lord Justice Leveson said the journalists "fear for their employment" if what they said could be attributed to them.
He added: "Although I would encourage all those who can contribute to this inquiry to do so on an open basis, I understand the concerns expressed by journalists who fear for their continued employment if they do not follow the line being taken by their employers.
"In the circumstances, given the broad remit of this part of the inquiry into culture, practices and ethics at a general, rather than a specific, level, I will be prepared to receive anonymous evidence."
