That the Parliament acknowledges the presence of unmarked graves outside former psychiatric hospitals across Scotland, 831 of which have been identified so far; understands that these graves represent the last resting place of patients of asylums and psychiatric hospitals who died in isolation and were interred without memorial in the care of the state; calls upon the Scottish Government to work with local authorities to identify these graves and to provide a fitting national memorial to commemorate all those buried in the grounds of psychiatric institutions over the centuries, and congratulates Clyde1, Forth1 and other local radio stations for uncovering the facts of this story through their "Lost Souls" investigation.
