Sikkim Krantikari Morcha (SKM) president Prem Singh Tamang, popularly known as P S Golay, took oath as the new chief minister of Sikkim on Monday.
The 51-year-old Golay was administered the oath of office by Governor Ganga Prasad at Paljor Stadium.
Golay is not a member of the state assembly at present as he did not contest the polls.
Hundreds of SKM supporters who were at the stadium cheered the 51-year-old party chief when he was taking the oath in Nepali language.
The SKM, founded in 2013, won a slender majority in the 32-member Sikkim Legislative Assembly by bagging 17 seats against 15 won by the SDF.
The Chamling government was ousted by the SKM after over 24 years.
The 11 SKM leaders who took the oath as ministers are Kunga Nima Lepcha, Sonam Lama, Bedu Singh Panth, Dr Mani Kumar Sharma, Arun Kumar Upreti, Sandup Lepcha, Lok Nath Sharma, Mingma Norbu Sherpa, Karma Loday Bhutia, Bhim Hang Limboo and Sanjit Kharel.
Though a total of three women, including one SKM candidate, won the polls, the Golay ministry has no woman representative.
