Raman Singh will be sworn-in as the chief minister of Chhattisgarh for the third consecutive time in Raipur on Thursday by state governor Shekhar Dutt.
Singh will be administered the oath of office at a ceremony which will begin at 11am at the Police Parade Ground.
A day after the Bharatiya Janata Party (BJP) secured a majority after winning 49 seats in the 90-seat state assembly, Singh was unanimously elected as a leader of the legislature party.
According to the party sources Singh will take the oath alone as the BJP has not announced the names of the legislators for the cabinet.
Sources said that Singh will have his ministerial team by next week.
"Singh will hold a discussion with the party's central leadership before finalising his team," party sources told Hindustan Times.
Top leaders of the BJP including LK Advani, BJP's prime ministerial candidate Narendra Modi, party president Rajnath Singh, leader of opposition in Lok Sabha Sushma Swaraj, leader of opposition in Rajya Sabha Arun Jaitley, Venkaiah Naidu will attend the ceremony.
Shivraj Singh Chouhan and Vasundhara Raje, chief minister-elects in Madhya Pradesh and Rajasthan respectively, will also be present.
Besides the top leaders of the BJP, Punjab chief minister Parkash Singh Badal will also be attending the swearing-in ceremony.
Tight security arrangements have been put in place in and around the ground.
An ayurvedic doctor-turned-politician, Singh retained his Rajnandgaon assembly constituency by defeating Congress candidate Alka Mudliya, wife of former Congress MLA Uday Mudliyar, who was killed in the Darbha Maoist attack, by a margin of 35,866 votes.
Singh now joins the club of BJP chief ministers who have scored hat-tricks in their respective states.
