As per the trend, the BJP is leading on eight seats followed by Rashtriya Janata Dal (RJD) (5), Janata Dal-United (3), Congress (2) and one each by Bahujan Samaj Party and Vikassheel Insaan Party (VIP). Counting of votes got underway at 8 a.m. for the three-phase Bihar Assembly elections that may herald a new era in state politics, with exit polls predicting a victory for the RJD-led Grand Alliance. The majic number for the winner is 122 in the 243-seat Bihar Assembly. The Janata Dal United-led National Democratic Alliance and the Rashtriya Janata Dal-led United Progressive alliance are the main contenders.
