PATNA: Bihar chief minister Nitish Kumar, who was scheduled to share dais with RJD supremo Lalu Prasad at the Nishad Adhikar Sankalp Maharally at Patna's Gandhi Maidan on Saturday, gave the function a miss, signaling the growing divide between the two leaders over terms of power-sharing and putting a question mark on the merger between the JD(U) and the RJD.
