Kumar made this clear to BJP President Nitin Gadkari when he met him during the oath taking ceremony of Pranab Mukherjee as President last month, sources close to the Bihar chief minister told PTI.
The sources said Gadkari had told Kumar that BJP has not discussed who would be its nominee for PM's post in 2014 Parliamentary polls and would definitely consult all NDA allies while finalising a name.
Sources added that the senior JD(U) leader told the BJP President that general elections are nearing as only one-and- half year is left, so it would be better if NDA finalises its nominee for the top post and insisted that Modi should not be chosen.
JD(U) with 29 MPs in Parliament is the second largest coalition partner of the NDA after BJP.
Kumar in a recent interview had said that NDA Prime Ministerial candidate should have secular credentials which was seen as his clear reservation over Modi's nomination for the post.
Nitish and Modi, the two top NDA leaders are not on good terms. The Bihar chief minister, who enjoys strong support of Muslims, did not allow Modi to campaign both in 2005 Assembly elections as well as in 2010 polls.
