BBC launches 'deception' review of shows
Ofcom this week imposed a £50,000 fine after a child in studio at the show posed as a competition winner to cover up a technical problem.
Corporation executive directors on Thursday ordered staff to report any concerns about programmes they had worked on since January 2005.
An e-mail was sent from director of vision Jana Bennett, deputy director general Mark Byford, director of news Helen Boaden, director of nations and regions Pat Loughrey and director of audio and music Jenny Abramsky.
It read: "As we have made clear, the principal mistake on Blue Peter was the deception of its audience.
"This issue is clearly not exclusively related to the use of premium-rate telephony. However it is central to maintaining audience trust in the BBC.
"Therefore as a matter of top priority I would now like to ask you to consult both your records and your colleagues to identify any further programmes where you feel there may be a risk that in some way audiences could have been misled."
