Set ups and stunts that combine investigation with factual entertainment should be editorially justified by the wrongdoing or other behaviour they expose - not simply for entertainment.
The factual entertainment approach to investigative journalism needs to be considered on a case by case basis; the fact a particular technique has been utilised on one programme does not mean it will necessarily be appropriate for another.
Production teams should keep in mind and work within the Editorial Guidelines on doorstepping when using set-ups as a means of getting answers to allegations of wrongdoing.
Production teams should keep in mind the laws relating to trespass, and normally leave private land or property when asked to do by the legal occupier.
If it is intended to secretly film a set-up or stunt and it is unlikely the subject of the filming would give retrospective consent, the secret filming should be justified by the public interest it serves.
Any deception should be in proportion to the wrongdoing or other behaviour under scrutiny and should not be solely for entertainment.
