Prison inspectors have said problems women are facing in getting sanitary products at Peterborough women's prison are ‘unacceptable’.
Prisoners had repeatedly raised the issue to inspectors in March. They have said the problems must now be resolved as a ‘matter of urgency’.
There were several areas of good practice at HMP Peterborough, according to chief inspector of prisons Charlie Taylor, but he raised some concerns.
Inspectors were also told some felt suicidal having only been allowed out of their cell for one hour a day.
He added the prison was safe and well ordered.
HMP Peterborough is run by Sodexo and holds around 300 adult and young women serving various sentence lengths.
