An extra £1m a year would be needed to carry out all the changes outlined in an inspection of Jersey's La Moye Prison, the Home Affairs Minister says.
The report says £2m needs to be spent on the prison
Minister Wendy Kinnard made the comments while explaining why few changes have been made to the prison since a report published in 2001.
Another report looking at the prison in 2005 said few recommendations had been embraced since 2001 publication.
Senator Kinnard said it was because of a lack of support from the States.
She was responding to questions made by Deputy Roy Le Herissier about the 2001 report.
The 2005 report by Her Majesty's Inspectorate of Prisons said relations between staff and inmates were good.
But it went on to say there are problems with bullying and living conditions, with the safety and security of inmates under threat.
It also described cases of racism and added few of the inspectorate's recommendations had actually been embraced since the 2001 report.
It also said at least £2m needed to be spent on it.
Deputy Le Herissier said he would keep up the pressure on the Home Affairs Department until changes started to be made.
