There was a perceptible "strong wave" in favour of the RJD-LJP combine and the days for Nitish Kumar as chief minister are numbered, the duo said in a joint press conference in Bihar.
"Kumar will disappear from the political scene in Bihar from November 24, the day of counting," Prasad said.
He held United Progressive Alliance government at the Centre and Nitish Kumar government in the state responsible for the price spiral and promised that on coming to power, his first step would be to control the rising prices of essential commodities in Bihar.
Paswan claimed that the alliance would win all the 26 seats going to poll in the sixth and the final phase of elections in Bihar on November 20. He said RJD-LJP combine would form the government with Prasad as Chief Minister and Pashupati Kumar Paras, the state LJP chief as his deputy along with another from a minority community.
He also vowed to ensure speedy trial of the case pending in a court against Kumar in connection with killing of a Congress worker at a booth at Pandarak in 1998.
Paswan said all promises made by the alliance in the joint election manifesto would be fulfilled in a time-bound manner.
