Toilet arrangements at one of Britain's five high security prisons are "grossly inadequate" and should be remedied urgently, according to a report published today.

Sixty per cent of inmates at HMP Long Lartin, Worcestershire, have no in-cell toilet and Government inspectors who made an unannounced visit to the prison last year said they found parcels of excrement thrown from windows littering the ground.

Anne Owers, Chief Inspector of Prisons, said the night sanitation system at Long Lartin inhibited the prison, which holds some of Britain's most dangerous criminals, from achieving a decent environment.

Speaking after publication of the report, which was based on a follow-up inspection made last September, Ms Owers said: "Long Lartin is inhibited in achieving a decent environment by the consequences of a grossly inadequate night sanitation system.

"However, in many other areas, including purposeful activity and resettlement, staff and managers are to be commended for what they have achieved." ..SUPL:
