Urfan Sharif, 42, was accused of Sara Sharif’s murder alongside his partner, 30-year-old Beinash Batool.
His brother, 29-year-old Faisal Malik, was found guilty of causing or allowing the girl’s death.
Police found Sara’s body under a blanket in a bunk bed at her home in Woking, south-west of London, on August 10, 2023, with dozens of injuries including extensive bruising, burns and fractures.
A post-mortem examination concluded she died of unnatural causes.
