What was lost when Britain unified defence ministries?

What are the advantages and disadvantages of defence unification and abolishing separate ministers for the armed services?

Unified direction makes sense, but Britain would benefit from restoring ministers who are directly responsible for representing each service beneath the Defence Secretary.

A single Secretary of State for Defence fits a world of joint operations and common procurement, but the panel argues that abolishing the individual service ministers removed dedicated political advocates. A larger ministerial team could retain shared portfolios for procurement, personnel, and veterans while giving the Navy, Army, and Air Force identifiable representatives. The institutional point is accountability: each service needs someone whose job is to understand and argue its case within government.
