Associated Newspapers is carrying out a review of editorial controls and procedures in the wake of the phone-hacking scandal.
Head of editorial legal standards at the publisher Liz Hartley has brought in former group legal advisor Eddie Young to assist her in the review.
The move comes ahead of the Leveson Inquiry into press standards which is set to subject all the national newspapers to a great level of scrutiny.
Trinity Mirror revealed on 26 July that it would be conducting a review of its editorial controls and procedures led by group legal director Paul Vickers.
News Corp has created a Management and Standards Committee headed by Lord Grabiner QC to review editorial procedures across its News Internaitonal titles and to work with the various inquiries looking into the phone-hacking scandal.
Last month Daily Mail editor Paul Dacre said he had never "countenanced" hacking or blagging on his newspaper.
He said "questionable methods can be justified" if there is "a great public interest in revealing wrongdoing", but added that hacking and blagging were "criminal charges".
Associated Newspapers banned its journalists from using inquiry agents in 2007 following the Information Commissioner's report What Price Privacy Now which placed the Daily Mail at the top of a table of a newspapers which bought information from private detective Steve Whittamore.
