Children in Powys are being put at risk of harm because of failings in social services, according to inspectors.
The report, by the Care and Social Services Inspectorate Wales (CSSIW), found a significant number of serious concerns over performance, quality and delivery of children's services.
These failing were made worse by 'poor and confused direction and weak governance', according to inspectors.
'Lack of assessment in child protection services' was also one of the main reasons children are at 'considerable risk'.
The Welsh Government's minister for Social Services Rebecca Evans has now issued a warning notice to the council.
Powys County Council says it accepts the findings and has apologised.
We fully accept the regulators recommendations, their report is both hard hitting and challenging. We are sorry that we failed to meet the high standards residents deserve and apologise for our shortcomings.
Minister for Social Services Rebecca Evans has given the council 90 days to improve.
I have serious concerns about Powys Children's Services and I am today issuing a Warning Notice to Powys County Council. This is a serious step but the reports findings are such that they require strong action to be taken.
The watchdog has set out action steps including appointing an interim director and an improvement board.
The First Minister said council faces being taken over by ministers if it doesn't improve.
