Mark Fairhurst, national chair of the POA, said: "The evidence we have heard from prison officers across the country about the condition of the UK's jails is a damning indictment of privatised prison maintenance - a system that is failing at every level.
The Prison Officers Association (POA) called on Labour to bring maintenance contracts back "in house" after previous decisions had been an "unmitigated disaster" and created a system that is "failing at every level".
Testimonies in the report from prison officers working in England and Wales revealed a "crumbling estate, rodent infestations and appalling conditions" for staff and prisoners.
The POA highlighted how courts in the Netherlands and Germany had previously refused to extradite suspected drug smugglers back to the UK due to concerns the prison conditions were "inhumane".
A Ministry Of Justice spokesperson told Sky News: "This government inherited a prisons system in crisis - with crumbling infrastructure, dangerous prisons and hard-working staff under immense pressure.
