A press story giving details of likely changes to the BBC's editorial rules has been described as "speculation" by the BBC.
The BBC's conduct has been scrutinised by the Hutton Inquiry
The Guardian reported that contentious stories based on single unnamed sources would have to be scripted in future.
The BBC would not confirm details but is expected to announce changes soon.
Scientist Dr David Kelly apparently killed himself after being named as the suspected source for a BBC report that a dossier about Iraq was "sexed up".
BBC reporter Andrew Gilligan has said he tried to report Dr Kelly's views accurately in his unscripted exchange on BBC Radio 4's Today programme, but acknowledged he had inadvertently made some mistakes.
His first report suggested the government "sexed up" a dossier on Iraq's weapons of mass destruction.
It prompted a row between the BBC and the government over the validity of the information in the report, and who had been behind it.
The conduct of the BBC and the government has been scrutinised by Lord Hutton's inquiry into Dr Kelly's death.
Lord Hutton is expected to publish his conclusions in the new year. His report could include criticism for the BBC and the government.
The Guardian also reported that the BBC would stop its high-profile journalists writing newspaper columns.
The BBC has already taken steps to overhaul its procedures.
Last week, the corporation appointed a deputy director general, Mark Byford, to head a new complaints and compliance system.
