An advisor to the National Council for the Training of Journalists (NCTJ) has left his position after it was revealed that he had not disclosed a prior conviction for downloading child pornography, reports Hold The Front Page.

Andy Bull, a former Express executive who had previously worked for the Daily Mail, the Independent, Mail on Sunday, The Times and AOL, was appointed to the NCTJ with responsibility for gathering opinions on changes to the training of press photographers, and had begun consultation with other organisations just days previously.

Bull was sentenced in January 2004 to four concurrent sentences of three months each for making indecent photographs of children – the legal charge for downloading child pornography – following an Operation Ore investigation. He previously wrote about the experience for The Times

A spokesperson for the NCTJ told Hold The Front Page: “We regret that these matters were not brought to our attention by Andy Bull and under the circumstances have decided it is not appropriate for him to have a future involvement with the NCTJ.”
