Children's services in Tameside have been downgraded to ‘inadequate’ in Ofsted's latest report.
Tameside Council was branded ‘inadequate’ for children needing help and protection, and also 'inadequate' in leadership, management and governance.
The report criticised managers and identified a huge backlog of cases.
More than 350 cases were waiting to be dealt with at the time of the inspection and more than 150 children considered at ‘medium’ risk of domestic abuse were still to be assessed.
Although none of those children were said to be at immediate risk of harm, the council was criticised for failing to deal with the backlog, leaving some children waiting up to two months.
Council leaders say the cases have now been cleared and say they are developing a response and planning an improvement journey.
