"The merger vehicle of Janata Parivar is on track and the vehicle is on the run," Kumar told reporters after a conclave on skill development here. "I think the merger will not take much time," he said.
"The date of the next meeting on merger will be decided soon in which everything will become clear," Kumar said.
Kumar, during his recent stay in Delhi, had met Samajwadi Party president Mulayam Singh Yadav, who has been authorised to decide modalities for the merger of Janata Parivar, RJD chief Lalu Prasad and INLD chief Om Prakash Chautala in a bid to speed up the process.
"On March 27, I, Lalu Prasad, Sharad Yadav and Mulayam Singh Yadav held detailed talks on merger issue," Kumar, who is playing a significant role in the amalgam exercise, said.
The coming together of splinter parties of old Janata Parivar before Assembly poll in Bihar later this year would be a decisive factor to give BJP a strong challenge.
