# Defence and Security Media Advisory Committee **Domain:** United Kingdom / Media Governance / National Security **Doc Type:** Institutional Node **Maturity:** Developed ## Definition **The Defence and Security Media Advisory Committee administers the United Kingdom's voluntary system of national-security publication notices, historically known as D-Notices.** Government and media representatives use the arrangement to advise against publication of information judged damaging to national security. ## War With Empire Context [[articles/war with empire/The Real Deep State Is British|The Real Deep State Is British]] presents the committee as a durable state–press interface whose notices lack direct statutory force yet can shape publication through professional compliance and access relationships. ## Analytical Boundary The existence of a notice establishes an advisory intervention, not automatic proof that later silence was caused by it. Causal claims require evidence from editorial decisions and publication history. ## Key Insight **A voluntary interface can become institutional governance when the parties sustain compliance across generations.** ## See Also [[wiki/Voluntary Censorship|Voluntary Censorship]], [[wiki/Secrecy|Secrecy]], [[wiki/Narrative Sovereignty|Narrative Sovereignty]], [[wiki/Deep State|Deep State]]
