Gandhi, who was here to attend the swearing-in ceremony, announced Singh's name as Congress Legislature Party (CLP) leader at a function at state Congress headquarter Sadaquat Ashram.
Sadanand Singh, ninth term MLA from Kahalgaon in Bhagalpur district, was considered a sure shot in the new Bihar cabinet but his name was not there among those who took oath.
Gandhi went to Sadaquat Ashram after the swearing-in and announced the new CLP leader's name but Singh and state Congress spokesman Binod Yadav could not reach there due to a traffic jam.
When asked by PTI whether he was happy being the CLP leader and not a minister, Singh did not give a categorical answer and merely said as a disciplined worker of the party he would perform whatever responsibility was entrusted to him.
