"On the pattern of Bihar, a government of grand alliance would be formed in Jharkhand after elections," Prasad said while appealing to the people of Hussainabad in Palamau district to cast their vote in favour of RJD's sitting MLA Sanjay Kumar Singh Yadav.
Despite his efforts, Prasad could not forge a pre-poll alliance as ruling partners JMM and Congress separated to contest the Assembly elections.
While JMM is contesting on its own, Congress and RJD have shared seats in the five-phase elections in Jharkhand with the first phase scheduled on November 25.
Prasad alleged that if BJP came to power in Jharkhand, "loot by corporate sector" would increase.
The former Bihar chief minster alleged that forces were out to stamp out socialists, which would not be tolerated.
