The POA has condemned the announcement by the Secretary of State for Justice that he intends to close four prisons - including one in Northallerton, North Yorkshire.
It says the prison service is in crisis, with staffing levels and morale at an all-time low and that the closures come "at a time when 20,000 prisoners are being held in an overcrowded prison estate, alongside the unacceptable level of violence and serious assults."
