Lalu Prasad had said Wednesday that he would work hard for a strong secular formation to defeat communal forces in the 2014 general elections.
According to leaders close to Lalu Prasad, RJD has agreed to part with eight or 10 of 40 Bihar Lok Sabha seats for Congress, four for Ramvilas Paswan's Lok Janshakti Party, and two for the Left parties.
"RJD will always favour alliance with the Congress and LJP as our past experiences show good performance when we contested together, than when we contested alone," senior RJD leader Ram Chandra Purve said.
