One of the country's most well-known prisons has been heavily criticised by inspectors who said it was "filthy", unsafe and under-resourced.
Inspectors said Wormwood Scrubs in west London had "shockingly" failed to put in place recommendations to tackle suicide and self-harm among inmates.
A report from Her Majesty's Inspectorate of Prisons (HMIP) put some of the failings down to a mass exodus of experienced staff after a restructuring last year.
HMIP found many cells meant for one prisoner were holding two, many windows were broken and some of the toilets were filthy.
The report also noted that a "significant" backlog of around 100 new prisoners meant the prison was not coping with the volumes of inmates arriving.
