Executives, editors and journalists from the Trinity Mirror Group have appeared before Leveson today.Richard Wallace, editor of the Daily Mirror, was questioned over the paper's libellous coverage of Chris Jefferies. He said it was a "black mark on his editing record” and that “Mr Jefferies’ name will be imprinted on my brain forever more”. The Mirror was one of eight papers to pay damages to Jefferies last year.Wallace said the paper received off-the-record information from a police source, claiming Avon and Somerset police were certain they had “got their man” when Jefferies was arrested in December 2010. He was later cleared as a suspect in the murder of Joanna Yeates.Wallace told the inquiry that ethics were “embedded in the culture of his newsroom”, and he did not believe the Mirror had broken the criminal law under his editorship. He addressed a article raised when Sienna Miller gave evidence last year, which she claimed portrayed her as drunk when in fact playing with sick children at a charity event. He said it was a mistake to use a single source for the story and the accompanying picture was not meant to be misleading, but had been cropped as the paper did not have permission to print images of the child present.Wallace said he could not recall the source of a story revealing a relationship between Ulrika Johnson and Sven Goran Erikson. He added that there “might well have been phone-hacking at the Mirror, although not to his knowledge.The editor of the Sunday Mirror, Tina Weaver, said she was not aware of phone-hacking at Trinity Mirror publications, and rebutted claims made by Newsnight in 2011 that hacking took place at her paper.She agreed that the PCC does not have “teeth” but said it was an effective mediator, and discussed a story on the private life of footballer Rio Ferdinand published in the Sunday Mirror last year. Ferdinand took the paper to court for misuse of private information but lost on the grounds of public interest. She added that a “series of injunctions rained down on us like confetti about a year ago” and the public interest and what interests the public often overlap.Andrew Penman, Mirror investigations editor, spoke briefly about prior notification. He warned that compulsory notification could alert “crooks and fraudsters” to investigatory work, but that he generally put stories to his subjects in order to elicit information.Lloyd Embley, editor of the People, was asked about a story claiming Charlotte Church had proposed to a boyfriend in a karaoke bar. He said the singer is currently seeking damages for defamation.He told the inquiry that he saw two to five sets of pictures a week that are not published “simply on the grounds of intrusion”, and that he turned down pictures of Kate Middleton after palace sources expressed concern that she was being stalked by the press.Embley said Sly Bailey, CEO of Trinity Mirror, had been “completely supportive” of his decision to make the paper politically independent.Bailey was last to the stand. She told the inquiry that the board had decided to fire Piers Morgan, following the publishing of hoax photographs in the Mirror, because they “lost confidence” in him as an editor. She said she had not heard about Morgan allegedly listening to a voicemail left by Paul McCartney for Heather Mills, echoing other Trinity Mirror witnesses.She said Richard Wallace had assured her “how very sorry he is” over the Jefferies coverage and said he had made “thousands and thousands” of good decisions. She added: “Sometimes our editors do get it wrong”.Bailey said there had not been a detailed investigation into phone-hacking at TMG as there was “no evidence” to suggest it had taken place in the company and had taken a “forward-thinking approach”.She was questioned over the Chris Atkins documentary Starsuckers, which showed the filmmaker offering celebrity stories he had fabricated to newspapers, and replied she “took comfort” from the fact her journalists had not paid for or published the information.Bailey told Lord Justice Leveson that she agreed with the “three pillar” model of regulation emerging from the inquiry, referring to elements of compliance, standards and arbitration.Statements from Paul Vickers, Vijay Vaghela, Kevin O’Sullivan and Vincent Moss, taken as read, are available on the inquiry website.
