National Democratic Alliance (NDA) presidential nominee Ram Nath Kovind on Wednesday met Bharatiya Janata Party (BJP) veterans LK Advani and Murli Manohar Joshi, who were seen as contenders for the candidature.
He is scheduled to meet ailing former prime minister Atal Bihari Vajpayee on Thursday.
BJP sources said Kovind (71) paid a courtesy visit to the two leaders credited with playing a key role in the saffron party's growth.
He met Advani (89) in the evening and visited 83-year-old Joshi's residence earlier in the day.
There was talk about Advani and Joshi being considered by the BJP as its pick for the president's post.
