The BJP and the Sena, which fought the last month's Assembly polls in an alliance, secured a comfortable majority by winning 105 and 56 seats respectively.
The BJP on Sunday expressed confidence that Maharashtra Chief Minister Devendra Fadnavis will prove his government's majority in the state Assembly, claiming he has the support of more than 170 MLAs.
After continuing to retain his position in Maharashtra after a long battle between the Saffron party and Shiv Sena, BJP's Devendra Fadnavis said 'Modi hai toh mumkin hai,' while greeting the party workers outside the office.
Congratulating Devendra Fadnavis on becoming the chief minister of Maharashtra once again, Union minister Prakash Javadekar on Saturday said the Shiv Sena betrayed the people of the state by deciding to go with the Congress, which was "synonymous with corruption".
Shah tweeted his congratulation to Fadnavis and NCP leader Ajit Pawar, who was sworn in as the deputy chief minister, after the oath-taking ceremony.
It is to be mentioned that elections were held on October 21 for the 288 seats of the Maharashtra Legislative Assembly and the results came on October 24.
The surprise swearing-in is being described as a political masterstroke of Sharad Pawar, who on Thursday night had said there was a consensus among the NCP, Congress and Shiv Sena that Uddhav Thackeray should lead the new government.
Former Maharashtra chief minister Devendra Fadnavis was on Sunday subjected to sloganeering by a section of Shiv Sena workers as he left Shivaji Park in the metropolis after paying tribute to Bal Thackeray on his ninth death anniversary.
