The Sun's deputy editor Geoff Webster has denied charges relating to the alleged payment of public officials for stories.
The 54-year-old pleaded not guilty to two charges of conspiracy to commit misconduct in public office at the Old Bailey.
The first alleges that between January 1, 2004 and January 31, 2012 he conspired with others to commit misconduct in a public office and the second that he conspired with persons unknown between November 3 and 6, 2010.
Webster, from Goudhurst in Kent, is said to have authorised payments by journalists to public officials.
The charges against him arise from Operation Elveden, Scotland Yard's investigation into payments to public officials.
