The Leveson Inquiry will set out the publication timetable for its report on Thursday morning, Culture Secretary Maria Miller has told the Commons.
The report will include the findings of Lord Justice Leveson into the culture, practices and ethics of the media following several months of hearings.
The Leveson report is due to be the first of two parts of an investigation into the role of the press and police in the phone-hacking scandal and was ordered by Prime Minister David Cameron in July last year.
Mrs Miller said: "I expect Lord Justice Leveson to deliver his report by the end of the month and the inquiry team will be making an announcement about specific times this morning."
She urged MPs to await next week's publication before rushing to judgment on how to reform newspaper regulation, but she said the status quo was "not an option".
Speaking at Commons questions, she added: "The principles that will drive any solution to the problems we face with regards to the press are that we need to have an independent regulator that needs to be tough and certainly doing everything to preserve free speech."
