Structure
Senior Management
Mark Hollingsworth and Nick Fielding give the following list of senior officers
- Director General (DG)
- Deputy Director General (DDG)
- Director and Co-ordinator of Intelligence (Northern Ireland)
- Legal Advisor to the Security Service[1]
Management Board
According to the MI5 website, the Director General, Deputy Director General and Legal Advisor make up the Management Board of the Service, along with seven branch Directors. The board is supplemented by two Non-Executive Directors from outside the Service in an advisory role.[2]
Branches
The following list is taken from the 2003 edition of Hollingsworth and Fielding's Defending the Realm: Inside MI5 and the War on Terrorism and may now be somewhat dated.[3] This is supplemented with branch descriptions from the MI5 website in italics where these seem to match Hollingsworth and Fielding's account.[4]
There are some differences between the two accounts. According to the website, international counter-terrorism and counter-espionage are the the responsibility of a single branch, suggesting that Hollingsworth and Fielding's D and G branches may have been merged or re-organised. The website also lists a separate Information Services and Technology Capability branch, suggesting that information technology may have been separated from H Branch.
