A further four prisons are to due close, the Government has said, as it confirmed plans to build two new "super" jails in England and Wales.
Blundeston in Suffolk, Dorchester, in West Dorset, Northallerton in North Yorkshire and Reading prisons will close, the Ministry of Justice (MoJ) said.
The announcement was made as the MoJ confirmed plans to build a 2,000-place new prison in Wrexham, North Wales. Feasibility work has also started on a second large prison to be constructed in the south east of England.
The work will focus on the possibility of replacing the existing Feltham Young Offenders Institution in west London with a large new adult prison and a new youth facility on adjoining sites in west London.
