In 1979, after a period of instability, a popular ministry headed by Nar Bahadur Bhandari, leader of the Sikkim Sangram Parishad Party, was sworn in. Bhandari held on to power in the 1984 and 1989 elections. In the 1994 elections, Pawan Kumar Chamling of the Sikkim Democratic Front became the Chief Minister of the state. Chamling and his party have since held on to power by winning the 1999, 2004, 2009 and 2014 elections. Currently, the Governor of Sikkim is Ganga Prasad.

The district capitals are Gangtok, Mangan, Namchi and Gyalshing respectively. These four districts are further divided into 16 subdivisions; Pakyong, Rongli, Rangpo and Gangtok are the subdivisions of the East district. Soreng, Yuksom, Gyalshing and Dentam are the subdivisions of the West district. Chungthang, Dzongu, Kabi and Mangan are the subdivisions of the North district. Ravongla, Jorethang, Namchi and Yangyang are the subdivisions of the South district. Each of Sikkim's districts is overseen by a state government appointee, the district collector, who is in charge of the administration of the civilian areas of the district. The Indian Army has control over a large part of the state, as Sikkim forms part of a sensitive border area with China. Many areas are restricted to foreigners, and official permits are needed to visit them. Sikkim is situated in an ecological hotspot of the lower Himalayas, one of only three among the ecoregions of India. The forested regions of the state exhibit a diverse range of fauna and flora. Owing to its altitudinal gradation, the state has a wide variety of plants, from tropical species to temperate, alpine and tundra ones, and is perhaps one of the few regions to exhibit such a diversity within such a small area.
