A women's prison has been criticised for not being adequately prepared after it was converted from a men's prison.
The prison says mental health services have improved
Buckley Hall prison, in Rochdale, did not cope with increased demand for mental health services, Her Majesty's Inspector of Prisons says.
The report said managers did not recognise women inmates are three times more likely to need mental health care than men.
But job training and cracking down on bullying was praised by the report.
Although staff prevented three suicides before last February's inspection, an inmate killed herself in May this year.
The prison says more psychiatric nurses have been employed to deal with mental health problems and the situation has improved.
