The Ministry of Home and Cultural Affairs (Dzongkha: ནང་སྲིད་ལྷན་ཁག་; Wylie: nang-srid lhan-khag; "Nangsi Lhenkhag") renamed as Ministry of Home Affairs[1] is the government ministry within the Lhengye Zhungtshog (Council of Ministers) which oversees law and order; the civil administration; immigration services; the issuance of citizenship documents, and other related documents; the delivery of services by local governments; and the preservation, promotion, development, and protection of the culture and heritage of Bhutan.

On May 20, 1968, the National Assembly, in its 28th session, formed a council of Ministers because of the increasing number of development activities in Bhutan.

[3] Under the first incarnation of the Lhengye Zhungtshog, as under the "CCM," Ministers continued to enjoy five-year terms while the Chair rotated among them on a yearly basis.

The Home Minister carries out part of the Lhengye Zhungtshog's Constitutionally mandated duty to aid, advise, and inform the King about the affairs of the State.

[4] The Bureau of Law and Order provides legal advice and guidance; facilitates prosecution; conducts research; reviews security clearance cases and verifies adverse records; and regulates explosives.

[6] The Administrative and Finance Division implements the policy of the government to have a small, efficient and compact civil staff.

Following the devolution of the executive authority to the elected Lhengye Zhungtshog in June 1998, the body was reconstituted for the third time in September 1998 with 15 members for three-year terms with Lyonpo Thinley Gyamtsho as its chairman.
