Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what progress he has made on (a) appointing service chiefs for four years tenures and (b) reviewing the performance of service chiefs two years after their appointment.
Service Chiefs are appointed for three years. After 18 months in post, an extension of one additional year (to four years) may be considered, factoring in performance and succession planning requirements.
The Chief of the Defence Staff, Chief of the Naval Staff and Commander UK Strategic Command have all had their postings extended to four years.
All British military personnel, including Service Chiefs, receive an annual performance review.
