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.
Former Assistant Commissioner in the London Metropolitan Police Service (2006-2011), Yates had resigned from office following criticism of his close relationship with journalists, in particular those from the News of the World. He gave evidence to the Inquiry two years after that resignation. Yates had been conducting a review of the 2006 Police Inquiry into the News of the World royal phone-hacking scandal. Lord Justice Leveson said it was a matter of "regret" that Yates had not handed the task to another officer but that there was no evidence he had been involved in corruption.
