Four councils in the North West are "inadequate" at caring for some of the most vulnerable children in society, a report has found.
The standard of child protection at Blackpool, Cheshire East, Cumbria and Rochdale councils is "unacceptably poor", Ofsted has warned.
The watchdog which inspects children's social care including child protective services, said more needs to be done to address "incompetent and ineffective" leadership in children's services.
It said some managers do not have a "firm understanding" of what constitutes good practice.
