"There are several names doing the rounds for the post of PM. But Bihar Chief Minister Nitish Kumar is best among them," JD-U legislator from Chandi, Hari Kishore Singh told IANS by telephone.
"Going by the reputation and experience of governance with justice, Nitish Kumar ranks first among those in the race for the post," added Singh, who is also vice chairman of the Bihar State Planning Board.
He said that without Nitish Kumar's support, no party would be able to form a government at the centre.
Singh criticised Bharatiya Janata Party leader Yashwant Sinha for supporting Modi as the party's prime ministerial candidate for the 2014 Lok Sabha elections.
The JD-U is the second-largest party in the BJP-led National Democratic Alliance (NDA).
