Vijay Rupani and Nitin Patel were on Sunday sworn in as the Chief Minister and Deputy Chief Minister of Gujarat respectively at Mahatma Mandi in Gujarat.
Governor OP Kohli administered the oath of office and secrecy to Rupani, Patel and 22 others.
The Eight cabinet-rank ministers, including Nitin Patel, and 16 ministers of state were also sworn-in.
The seven cabinet ministers who were sworn in during Sunday's ceremony are Bhupendrasinh, Babu Bokhiria, Dilip Thakor, Atmaram Parmar, Ganpat Vasava, Jayesh Radadiya and Chiman Sapariya.
60-year-old Rupani met Governor O P Kohli and staked claim to form the government, a day after he was elected by BJP legislators to succeed Anandiben Patel, with the central leadership playing a vital role in the choice.
The new government - sworn in after former BJP CM Anandiben Patel resigned last week - is expected to shoulder the responsibility of steering BJP to victory in the high stakes 2017 assembly polls in Gujarat. The state has been beset with trouble lately with the Patidar stir and with anti- Dalit atrocities like the flogging of dalits in Una.
Nine ministers from the previous cabinet, including some considered as loyalists of outgoing chief minister Anandiben Patel, have been dropped.
The oath-taking ceremony was held in the presence of top BJP leaders including its president Amit Shah, party veteran L.K. Advani, Union finance minister Arun Jaitley and Union science and technology minister Harsh Vardhan.
The chief ministers of Maharashtra, Jharkhand and Haryana—Devendra Fadnavis, Raghubar Das and Manohar Lal Khattar, respectively,—were among the other dignitaries present on the occasion.
For weeks before the announcement Nitin Patel was seen as the popular choice for the position. He was also Anandiben Patel's first choice to replace her. But in a dramatic turn-around Rupani — a non-Patel — was announced to the seat. Many believe that his status as a Amit Shah loyalist got him the CM seat.
It was widely speculated that Anandiben Patel was unhappy with the party president's choice, however a compromise was achieved when Nitin Patel was made the Deputy CM.
Rupani, who came up through the RSS, is being assigned the task of leading BJP in the polls at a time when BJP is struggling to retain its political base. The party has also been affected by the absence of leaders of Modi's caliber in the state.
