People held in immigration removal centres have a range of vulnerabilities relating both to disappointment at imminent removal from the country of hoped-for residence and various antecedent difficulties. An important subgroup in the UK is of foreign national ex-prisoners who have served a period of incarceration there. Prisoners generally have higher rates of mental disorders than the general population. It is, however, not clear whether foreign national ex-prisoners in UK immigration removal centres have higher rates of mental disorders than other detainees.
