"If he (Advani) is not at the helm of affairs, it will be very difficult for us to continue in the alliance," party general secretary K C Tyagi told reporters.
Raising the party's pitch for a "secular" PM candidate, Tyagi said the party was not commenting on Modi's elevation as the campaign committee chief, but "NDA's prime ministerial candidate should be secular, have a clean and progressive image. We will not compromise on the issue of secularism."
"NDA was forged with the efforts of Atalji and Advaniji. He (Advani) is also the working president and Atalji (Atal Bihari Vajpayee) is not keeping well.
"So his (Advani) resignation in my opinion is a serious issue and we will convene our own party meeting to discuss the matter...Advanji's resignation is not good for NDA's health," Yadav, who is also the convenor of the NDA, had said.
Advani, one of the founding members of BJP, resigned from the party Parliamentary Board, Election Committee and National Executive, apparently opposing the elevation of his one-time protege Gujarat Chief Minister Narendra Modi as election campaign committee chief.
