Prison officers at maximum-security HMP Shotts near Glasgow, have passed a motion underlining their dissatisfaction with the prison's acting governor over claims of "dangerous decision making".
The no-confidence vote comes after officials from the Prison Officers' Association Scotland wrote to Scottish Prison Service bosses about three "dangerous" incidents at the Lanarkshire jail, reported the Daily Express.
The first incident that raised concerns about governor William Stuart relates to a contraband search operation in Lamont Hall which allegedly saw angered inmates begin to threatening staff.
