When asked if all non-NDA parties would come together in electing the next President, he said, "First of all the ruling party should try to form consensus".
The Bihar CM said "Modi became the Prime Minister because he was capable of taking over the post, and the people of our country voted him to power".
Nitish Kumar remark comes at a time when speculations are rife with the selection of candidates by ruling BJP and the opposition Congress.
Ms Banerjee arrived in the national capital this evening and is also likely to hold discussions with Delhi Chief Minister Arvind Kejriwal. "But if this does not happen, it becomes obligatory for the opposition parties to field their own candidate", he said.
Kumar's name gained currency as possible PM candidate against Modi in 2019, when NCP chief Sharad Pawar described him to be "PM material" and RJD president Lalu Prasad sounded as if he had endorsed this view, several months ago. "I know, I do not have that capacity", he was reported as saying. "It can not be drained in the river", he said, adding that his government will not tolerate if any river, specially the Ganges, was polluted by any means.
The Congress leader said, "As far as a united opposition is concerned, there will be many recommendations and there have to be deliberations on it".
"Besides, Mukherjee should also agree to it", a senior CPI-M leader said.
"It is the responsibility of the Centre to make efforts for a consensus on the candidate". Mr Kumar also wondered why people often projected him as a claimant for the PM's post.
The Presidential election is due in July. But for this, "the ruling alliance has to take the initiative for a consensus". Is there any need of reaction of a "third party" in these allegations and counter-allegations?
The party favoured Gopal Gandhi, a former bureaucrat and grandson of Mahatma Gandhi, for the job. "But the Centre has to see to it", Nitish said while reacting to queries on the presidential polls after his Lok Samvad (public interaction) programme.
