The former News of the World head of news told the Inquiry that he was ordered to deliberately deceive the McCann family after obtaining Kate McCann's personal diary.
He said that former editor Colin Myler had told Edmonson to phone the McCanns' spokesman Clarence Mitchell and inform him that the paper was running a story, record the call, but "certainly don't tell him that we're in possession of the complete diaries". This deception, according to Edmondson, was to prevent the McCanns from taking action that might stop publication.
Edmondson's claims were at odds with Myler's evidence to the Inquiry in December, in which he said he had been told by Edmondson that he had cleared the story with Mitchell.
However, Lord Justice Leveson said a transcript of a phone call between Edmondson and Mitchell about the story the paper was planning was "most clearly ambiguous".
