The death of a 17-month-old boy after months of abuse, despite him being on an at-risk register, has sparked a review of child protection in England.

It comes as two men were found guilty of causing his death in August 2007.

The boy, from Haringey, north London, suffered 50 injuries, and the case has revealed a series of failings by social workers, health workers and police.

The case is described as worse than that of Victoria Climbie, who was murdered in Haringey in 2000.
