Submitted in response to written requests from the Inquiry, usually providing lists of questions to be answered. In most cases these formed the basis of questioning in public sessions, but in some cases they were read into the record (or taken as read) and the witness did not appear in person.
Given by witnesses invited by the Inquiry, normally after they have made written statements. These sessions could be viewed live online and sometimes on television news services, and the video recordings are part of the archive. The statements were usually released to the public after the public sessions.
John Mulholland was editor of the The Observer at the time of the Inquiry, having worked for the Guardian Media Group since 1994. He gave evidence that all staff were obliged to abide by the PCC code of conduct as well as the more rigorous GNM editorial code. Contributors were similarly expected to abide by the codes. There were strict procedures in place for any journalist wishing to go undercover or use any form of subterfuge. The Observer had, he said, used the services of a private investigator under an earlier editor.
