Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what proportion of medical discharges from the Armed Forces were for mental and behavioural disorders in each of the last ten years.
Medical discharges in the UK Armed Forces involve a series of practices and protocols, which differ in each Service to meet their specific employment requirements. Due to these differences, data is presented separately for each Service.
The table below provides the numbers and percentage of UK Regular Armed Forces personnel who were medically discharged with a principal cause of mental and behavioural disorders between 1 April 2012 and 31 March 2022, by Service and financial year.
