Tamil Nadu chief minister Jayalalithaa who had come to Delhi for the Planning Commission meeting, said, it was BJP's internal matter. She however added that Narendra Modi was her personal friend. "Politically I think this is not the proper time to make any comment", she added.
Former UP chief minister Kalyan Singh appealed to Advani to withdraw his resignation.
BJP leader Sushma Swaraj said the party was confident of asking Advani to take back the resignation.
The Congress appeared happy over the BJP war.
"The BJP has to think. The concerned person has to think. We had already said it (Modi's elevation) will have repercussions," said Janardan Dwivedi of the Congress.
The Karachi-born Advani and the now ill Vajpayee have been for decades the two main pillars of the BJP and its predecessor Bharatiya Jana Sangh.
Advani joined the RSS in 1947 and the Jana Sangh when it was founded in 1951. He became the BJP president in 1986, when it had only two members in the Lok Sabha, and soon became a strong votary of the Ram temple movement, which helped the BJP to grow and grow.
