Singh had expressed concern that NDA will disintegrate if

Modi is projected as the BJP's prime ministerial candidate. Without taking his name, Kumar had publicly expressed his stiff opposition to Modi being projected as BJP's prime ministerial candidate and firmly advocated for a secular person with wider acceptability in cross section of the society to be projected as the candidate for the top post. Apart from the former union minister, some other senior BJP and JD(U) leaders too have been engaged in war of words with each other on the prime ministerial issue within the NDA recently with loyalists of both Modi and Kumar feverishly backing their leader's stature for being projected as the prime ministerial candidate.
