The cabinet can have 14 members, including the Chief Minister and the Deputy Chief Minister, with two slots kept for the future expansion.
Governor Satyadeo Narain Arya admistered oath to six Cabinet ministers and four Ministers of State (Independent charge) at a simple ceremony in Raj Bhawan that lasted less than an hour.
The government now has eight BJP ministers besides Chief Minister Manohar Lal Khattar (65), who is at the helm for his second consecutive term.
The saffron party's post-poll partner and alliance partner Jannayak Janta Party (JJP), a defector of the state's once prominent regional outfit Indian National Lok Dal (INLD), got lone minister Annop Dhanak along with Deputy Chief Minister Dushyant Chautala, 31, in the government.
The inducted council of ministers were six-time Ambala (Cantonment) legislator Anil Vij, who was Health Minister in the previous government; former Speaker and three-time Legislator Kanwar Pal Gujjar, who belong to the Other Backward Class category, and BJP's Dalit face Banwari Lal, who was previously a minister of state.
Khattar and Vij are from the Punjabi community.
The other Cabinet ministers from the BJP quota were two-time Legislator Mool Chand Sharma and first-timer J.P. Dalal.
The lone woman in the cabinet is BJP's Kamlesh Dhanda, who belongs to the Jat community that comprises 28 per cent of the state's population. Her husband Narsingh Dhanda was a former minister.
JJP's Dhanak was inducted as the Minister of State.
The lone Independent who got the Cabinet berth was Ranjit Chautala, estranged brother of INLD President O.P. Chautala. He was a minister in the Devi Lal cabinet.
