The chief inspector of prisons says an overcrowded jail is unsafe. Barlinnie is more than 50 per cent over capacity, which meant Brigadier Hugh Monro said it could not be regarded as "safe". He has called for a review of the management of overall prisoner numbers and wants an explanation of why so many men who have not yet faced a trial are held in the Glasgow prison. "The prison has an operational limit for very good reasons," he said.
