JMM executive president Hemant Soren will take oath as Jharkhand chief minister at Raj Bhavan on Thursday, an official said.
Congress state unit president Rajesh Thakur told PTI that the decision was taken in a meeting of coalition partners at Soren's residence here.
"Governor CP Radhakrishnan will administer the oath and office of secrecy to Hemant Soren at 5 pm at Raj Bhavan," the official said.
The JMM, earlier in the day, said Soren would take oath as the chief minister on July 7 after Governor CP Radhakrishnan invited him to form government in the state.
Later, the JMM-led coalition decided that Soren would take oath on Thursday.
Leaders of the JMM-led alliance in the state unanimously elected Hemant Soren as the legislature party leader.
Notably, Champai Soren resigned as chief minister on Wednesday and Hemant Soren, who is out on bail in a money laundering case, staked claim to form the government.
A JMM-led alliance delegation met Governor Radhakrishnan at Raj Bhavan on Wednesday.
"The governor has invited Soren to form government in the state and sought a date and time for the swearing-in ceremony," a Raj Bhavan official said.
The delegation headed by Hemant Soren comprised Congress state unit president Rajesh Thakur, RJD minister Satyanand Bhokta and CPI(ML)-L MLA Vinod Singh.
Kalpana Soren, the Gandey MLA and wife of Hemant Soren, was also part of the delegation.
