Patna; Throwing his weight behind BJP stalwart Atal Bihari Vajpayee, Bihar Chief Minister Nitish Kumar today said he is the 'undisputed leader' and the most suitable prime ministerial candidate if the NDA returns to power.

Reacting to reports that BJP president Rajnath Singh and his predecessor were interested in the post, the JD(U) leader whose party is a prominent constituent of NDA said "No vacancy exists for the time being. In case of a vacancy, we will think about it and inform the media."

"Vajpayee is the undisputed leader of the NDA at the moment and there will be no vacancy for the post of prime minister in case the NDA returns to power at the Centre," he told reporters at his residence.

Favouring reservation for socially and educationally backward Dalit Christians and Muslims, the chief minister said "The Centre is to take a decision in this regard. The state will abide by the decision".

"Bihar government has already formulated a ten point programme for the uplift of the minorities," the Chief Minister said.
