Former Formula 1 boss Max Mosley is expected to call for a new system of newspaper regulation when he appears before an inquiry into journalistic ethics on Wednesday.
Mr Mosley, who was the subject of a News of the World article alleging that he took part in a "sick Nazi orgy", has suggested the creation of a "press tribunal" in a written statement to the Leveson Inquiry.
And he is expected to outline his plans in detail when he appears before the inquiry in London.
Mr Mosley gave evidence to the inquiry in November, when he accused the government of having been "completely in the thrall of" newspaper bosses.
He is scheduled to return as inquiry chairman Lord Justice Leveson analyses options for newspaper regulation.
Mr Mosley was awarded a record £60,000 in privacy damages at the High Court after taking legal action against the News of the World for its March 2008 Nazi orgy story - which he denied.
