Six prisons in England are to be closed and three more will be partially shut, the Ministry of Justice has announced.
It will result in the loss of 2,600 places in what the statement called "old and uneconomic" prisons and is expected to save £63m per year from the cost of running prisons.
The six prisons that are to close are Bullwood Hall in Essex, Canterbury, Gloucester, Kingston in Portsmouth, Shepton Mallet in Somerset and Shrewsbury.
Prisons in Chelmsford, Hull and Isle of Wight are to be partially closed.
The Ministry of Justice says it also plans to build a new super prison with 2,000 places.
It is set to be around 25% bigger than the existing largest facility.
