D Branch is the division of MI5 responsible for non-terrorist threats and protective security, including counter-espionage. It is one of four operational branches which report to the Deputy Director General of the Security Service.[1]

History

The designation 'D Branch' has been applied to a variety of functions over the course of MI5's history.

1916-Imperial Intelligence

The earliest version of D Branch was created in 1916, shortly after the foundation of MI5, to cover imperial and overseas (including Irish) intelligence.[2]

1938-Protective Security

By 1929, MI5 had been reduced to two branches, A and B.[3] In 1938, D Branch was re-established with responsibility for protective security in munitions, aircraft factories and dockyards.[4]

1953-Counter-espionage

In Dick White's 1953 re-organisation of the Service, D Branch became the division responsible for counter-espionage.[5] From 1965-1970, Hugh Fraser worked for D Branch, where he "ran agents against Russian diplomats serving in Britain in an effort to establish whether they were actually KGB agents".[6]

In 1968, Michael Hanley was appointed head of D Branch, and carried out a re-organisation which led to its replacement with MI5 K Branch.[7]

1994-Non-terrorist threats

In MI5's organisation as of 1994, D Branch had been re-established. Its current incarnation includes elements of the former C Branch, F Branch and K Branch.
