Prisoners at one Kent jail need to be taught more skills to stop them re-offending, a report has found.

Inspectors found that at HMP Swaleside on the Isle of Sheppey, there is enough activity to meet the needs of only 80% of inmates.

During the working day, a quarter of all prisoners are kept locked in their cells, although this is an improvement on a previous visit by HM Inspectorate of Prisons.

The report, published this week, said Swaleside is a "fundamentally safe prison", with good relationships between staff and prisoners and good health care.

However, inspectors, who visited the prison in July, found a "significant" number of reported incidents of violence and told staff to improve segregation and the use of force.

Nick Hardwick, chief inspector of prisons, described the report as "positive", adding: "This inspection suggests the prison continues to build on its strengths but it still needs to get a strategic grip on the provision of purposeful activity and training."

Swaleside is a Category B jail and is part of the Sheppey Cluster of prisons, which also includes HMP Elmley and HMP Standford Hill.

Its eight wings can house up to 1,130 inmates.

Activities for prisoners include victim awareness and anger management courses, an education programme and employment opportunities.
