However, Sharad Yadav Saturday denied making such a statement.
Nitish Kumar said there is a strong possibility of a non-BJP and non-Congress formation by like minded parties including the JD-U, Left parties and other regional parties.
"We are keen on trying for a new front on the basis of understanding and cooperation to take on the Congress and the BJP in elections," he said.
Earlier, Nitish Kumar said talks were on "among like-minded parties" on forming a new front ahead of the Lok Sabha elections.
The chief minister said his party along with the Left parties, including the Communist Party of India-Marxist (CPI-M), had been working on forming a new political formation.
Nitish Kumar dumped the BJP in June last year and ended a 17-year-old alliance with the saffron party over its naming Narendra Modi as the prime ministerial candidate for this year's Lok Sabha polls.
