The mental health of foreign national prisoners.

Foreign national prisoners include people who are subject to criminal proceedings and have been deprived of their liberty in a state in which they are neither a national nor a resident. In the United Kingdom, they constitute approximately 10,000 individuals and represent around 12% of the total prison population. Significant health disparity exists within the general prison population compared to society at large and foreign national prisoners suffer even higher rates of both physical and mental health disorders.
