Jharkhand Mukti Morcha working president Hemant Soren on Tuesday met Jharkhand Governor Droupadi Murmu and staked claim to form government in the state.
Earlier in the day, he was formally elected as the JMM legislature party leader.
Soren, accompanied by leaders of his party, the Congress and Rashtriya Janata Dal -- which comprised the opposition alliance in the assembly polls -- called on the governor at Raj Bhavan to stake claim to form the new government.
He will take oath as the chief minister on December 29 at 1 pm, JMM general secretary Suprio Bhattacharya, who accompanied Soren to Raj Bhavan, said.
Meanwhile, a Raj Bhavan communique said that a delegation comprising the JMM, Congress and the RJD met the governor and staked claim to form the new government under Soren's leadership.
"The delegation comprising JMM, Congress and the Rashtriya Janata Dal met the governor at Raj Bhavan and apprised the governor that the newly-elected MLAs have chosen Hemant Soren as their legislature party leader," the communique said.
