To ask the Secretary of State for Defence how many members of the armed forces were (a) married, (b) cohabiting and (c) in a relationship when they joined the services in the latest period for which figures are available.
A personal status is recorded on the Joint Personnel Administration system on enlistment for the purposes of determining entitlement to some allowances and liability for dependent children, rather than the legal marital status of personnel. As these are private life matters there is no mandatory requirement for personnel to advise the Ministry of Defence if they are cohabiting or in a relationship.
Any information which is held would be on manual records, and could be obtained only by undertaking a manual search of records on multiple sites. This information could therefore be provided only at disproportionate cost.
