The two leaders discussed a range of issues including the party's internal affairs and the split in the NDA after BJP's old-time ally JD(U) parted ways after an alliance of 17 years.
On Janata Dal (United) Modi was plain and firm. Modi has told Advani that BJP doesn't need allies which are against it.
On his part, Advani told Modi that he didn't resign from party posts because of Modi's elevation as campaign committee head at the recent Goa conclave. Advani had resigned from key party posts after the Goa meet.
Advani, however, later withdrew his resignation following a telephonic talk with RSS chief Mohan Bhagwat and persuasion by BJP leaders.
Bhagwat is also expected to meet Advani and is likely to advise him to clarify the allegations he made in the letter.
Modi drove down to Advani's Prithviraj Road residence in Delhi and spent about an hour with the senior leader. He left without speaking to the waiting media contingent.
The Gujarat chief minister also spent more than an hour with ailing former prime minister Atal Behari Vajpayee at his residence.
Modi also met senior BJP leader Murli Manohar Joshi to express his gratitude. "Modiji has come to Delhi to express his gratitude over his recent appointment as Chairman of the BJP Campaign Committee at Goa. He has expressed his gratitude and said he is trying to fulfil the responsibility given to him," Joshi later told reporters.
Modi is visiting national capital for the first time after being made head of BJP's election campaign committee.
