He said his party is in touch with CPI-M leader Prakash Karat and CPI leader A B Bardhan over third front formation after polls and have an understanding on this.
"We feel that the third front government should come to power at the Centre. The country's next prime minister will be a third front candidate," he said.
Yadav, who has been spearheading the cause of a third front government and aspiring for the top post, said neither the BJP nor the Congress will be able to form the government.
Asked who will be the third front prime ministerial candidate, Yadav said only one Prime Ministerial candidate has been announced so far, in an apparent reference to BJP's Narendra Modi.
"But, the third front candidate will be the next prime minister of the country," he claimed.
