Rory Stewart said 'as many as 20' jails are in a similar state to HMP Birmingham
The minister responsible for prisons has said that synthetic drug spice is the "main driver" in deteriorating prison conditions across the country.
Rory Stewart said that "as many as 20" prisons were in a similar state to HMP Birmingham but asked to be judged on his record in 12 months time, having only been appointed in January.
Stewart said he "no longer had confidence" in G4S, the private contractor previously responsible for the prison before the government took over to implement emergency measures.
The chief inspector of prisons, Peter Clark, forced the prison back under state control after describing a "state of crisis" with "appalling violence and squalor."
Speaking to Tom Swarbrick on
LBC, Stewart said "The driver is new psychoactive substances, particularly spice, which are causing this very bizarre, aggressive behaviour from prisoners," citing as many as 20 other locations.
Prison service ratings from last year list 15 jails "of serious concern," including Birmingham, Nottingham and Exeter as well as Wandsworth and Wormwood Scrubs in London.
An MoJ spokesman said: "We have made no secret of the fact there are a number of prisons currently facing significant challenges across the estate.
"We monitor prison performance extremely closely. None are at the same level of concern as Birmingham, which faced a very particular set of circumstances leading to the decisive action we have taken."
