The BBC Trust has said that the airing of a Newsnight report which led to Lord McAlpine being wrongly named as a paedophile resulted largely from a failure by members of the team to follow the BBC's own editorial guidelines.
The broadcast on 2nd November was a "grave breach which had been costly to all concerned" and resulted in the public being misled, the Trust's Editorial Standards Committee (ESC) found
And in its findings, the committee ordered another report by the BBC next year into what steps will be taken to make sure the corporation "learns from these events".
