JD(U) on Monday gave first indications of parting ways with the NDA, saying it is "difficult" to remain in the alliance which is on "ventilator support" in the wake of resignation of LK Advani from top BJP posts and anointment of Narendra Modi as party's campaign committee chief for next Lok Sabha polls.
Terming Advani's resignation as a "serious issue" and "not good for NDA health," Janata Dal (United) president Sharad Yadav said his party, an NDA ally, will meet to review the latest developments.
"I am deeply saddened by the resignation of Advaniji. Because the NDA was forged with the efforts of Atalji and Advaniji. He (Advani) is also the working president and Atalji is not keeping well," Yadav said here.
"So his resignation in my opinion is a serious issue and we will convene our own party meeting to discuss the matter," said Yadav, who is also the convenor of the NDA.
In Patna, Bihar Chief Minister Nitish Kumar said JD(U), which is opposed to Modi's projection as BJP's prime ministerial candidate, will discuss all aspects of the dramatic developments and will spell out its stand soon.
"We will come out with our stand on the issue after examining the entire situation and considering all the aspects in the party", Kumar told reporters.
He also denied reports in a section of media that BJP President Rajnath Singh had talked to him before the decision on Modi's anointment.
Asked about JD(U) setting a deadline till November for BJP to declare its Prime Ministerial choice, he said, "We will choose the timing."
Kumar had made it clear that the BJP Prime Ministerial candidate should be one who is acceptable to all, which was interpreted by analysts as JD(U)'s no to Modi.
JD(U) is the second largest constituent of the BJP-led NDA. JD(U) and BJP have been ruling Bihar successfully under Kumar since 2005. NDA had bagged 34 out of 40 Lok Sabha seats in the 2009 Parliamentary polls.
JD(U) general secretary K C Tyagi said Advani has been "humiliated" and "NDA is now on ventillator support" and "it will be difficult for us" to continue to be in NDA.
