Some 485 children in England died or were seriously harmed by abuse or neglect in a year, a report by the child safeguarding practice review panel has revealed, as experts called for change in the wake of the murder of 10-year-old Sara Sharif.

Sara's school made a referral to Surrey CC's social services five months before her father Urfan Sharif and stepmother Beinash Batool murdered her last year, but the case was closed within days.
