'''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]].<ref>Michael Smith, The Spying Game, Politico's, 2003, pp.129-130.</ref>

==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.<ref>Christopher Andrew, Defence of the Realm, The Authorized History of MI5, Allen Lane, 2009, p.84.</ref>

===1938-Protective Security===
By 1929, [[MI5]] had been reduced to two branches, A and B.<ref>Christopher Andrew, Defence of the Realm, The Authorized History of MI5, Allen Lane, 2009, p.127.</ref> In 1938, D Branch was re-established with responsibility for protective security in munitions, aircraft factories and dockyards.<ref>Christopher Andrew, Defence of the Realm, The Authorized History of MI5, Allen Lane, 2009, p.134.</ref>

===1953-Counter-espionage===
In [[Dick White]]'s 1953 re-organisation of the Service, D Branch became the division responsible for counter-espionage.<ref>Christopher Andrew, Defence of the Realm, The Authorized History of MI5, Allen Lane, 2009, p.327.</ref>

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]].<ref>Peter Wright, Spycatcher: The Candid Autobiography of Senior Intelligence Officer, Viking, 1987, pp.332-334.</ref>

===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 [[MI5 C Branch|C Branch]], [[MI5 F Branch|F Branch]] and [[MI5 K Branch|K Branch]].
