Leader of the BJP legislature party Arjun Munda on Monday night staked claim to form government in Jharkhand.
Governor M Rama Jois will swear him in on Monday morning.
Munda, who was welfare minister in Babulal Marandi Cabinet, said he had submitted to Jois a list of 40 MLAS who were supporting him.
He said he expected two more legislators, including rebel tourism minister Joba Manjhi, to come out in his support.
