Due to the iminant negotiations over licence fees the BBC have put a "tempary" stop on the productuction of a fictitional version of the Shannon Mathews story as they think it's bad taste might upset their negotiations. Given that the events were inspired by a story line in the program "Shameless" the proposed program asks all sorts of questions, as to the level of taste at the BBC.
Another issue is their casting department, they do list the program as fiction yet the person chose to play Shannon's mother (above) does show how far they intend to move away from reality.
