Panorama looks into the circumstances surrounding the death of a 17-month-old baby.
A six-month investigation by the programme reveals the mistakes and missed opportunities that led to the death of the boy known only as Baby P.
He suffered horrific abuse, but the same social work department that was criticised in the Victoria Climbie case, never took him into care despite a number of warning signals and injuries.
Panorama: What Happened to Baby P? will be on BBC One on Monday 17 November at 8.30pm
