The Chief Constable of South Yorkshire Police, David Crompton, has announced he is to step down following criticism that handling of child sexual exploitation by his force was "inadequate".
It follows a review which criticised the force's handling of the Rotherham child sexual exploitation scandal.
The independent review was commissioned in the wake of the Jay Report, which found at least 1,400 girls were abused in Rotherham between 1997 and 2013.
It said police handling of sexual exploitation in South Yorkshire was "inadequate", and that attempts to alert senior officers to the issue had fallen on "deaf ears".
Following the announcement, South Yorkshire Police and Crime Commissioner Alan Billings paid tribute to David Crompton's service.
