The organisers initially covered the nameplate of Tejaswi, the special guest at the function whose seat was next to the chief minister's, but later removed it. The function was held to mark the World Youth Skills Day.
Kumar, who was seated next to Labour Resources Minister and RJD leader Vijay Prakash, subsequently swapped his chair with JD(U) minister Rajiv Ranjan Singh, who was on his right.
The episode, which was captured in still as well as video cameras of the electronic media, gave an indication of how the acrimony between the two Grand Alliance partners was growing with every passing day in the wake of the CBI registering an FIR against Tejaswi and others in connection with a land-for hotels scam case.
The developments on the dais at the newly-built Gyan Bhawan here came a day after RJD chief Lalu Prasad rejected the possibility of his son Tejaswi putting in his papers, a move seen as being dismissive of the JD(U) putting pressure on the deputy chief minister to quit.

"They (RJD) must come out with a rebuttal as part of the coalition 'dharma', so that the Mahagathbandhan's (Grand Alliance) image in terms of public probity is not damaged," he said.
Varma said, "An FIR has been registered. If Tejaswi or other members of Lalu Prasad's family believe they have been targeted and the charges against them are false or politically motivated, they need to place a factual and point-by-point rebuttal in the public realm."
The JD(U) has 71 MLAs and the Congress 27 while the BJP, which is the main opposition in the House, has 53.
The Assembly has representation from the CPI(ML), the HAM (Secular), the LJP and the RLSP among others.
