"I will continue my sincere efforts to speak to Paswan and discuss with him about formation of an Congress-RJD-LJP alliance for the general elections," Prasad told reporters here.
He said that he had made sincere efforts in recent days to speak to his LJP counterpart without success and would continue to do so.
The RJD chief stonewalled all controversial questions related to the LJP President and his son.
Asked about his reaction on the CBI proposing to question Paswan in the Bokaro Steel Plant recruitment scam, Prasad said "I will rather not say anything on the issue."
He also slammed senior BJP leader Sushil Kumar Modi saying "Modi is a vicious person who is trying to trying to create a wedge between Paswan and the UPA government by indulging in falsehood."
Prasad alleged it was the Bihar chief minister and his deputy who had worked to keep Paswan castemen out of the broad Mahadalit communities in Bihar.
