The meeting of Left leaders with DMK president and Tamil Nadu Chief Minister M Karunanidhi on Thursday on UPA's presidential nominee remained inconclusive, with consensus still eluding the ruling coalition.
Both the sides decided to meet again in the evening.
Left leaders Prakash Karat (CPI-M), AB Bardhan and D Raja (CPI) held discussions with Karunanidhi, who spoke with Prime Minister Manmohan Singh and Congress chief Sonia Gandhi on Wednesday night, for about 30 minutes in New Delhi.
Karat, CPI(M) General Secretary, said, "we exchanged views on the presidential issue and decided to meet again in the evening."
"The very fact we are meeting again in the evening shows we have not decided on any names," Bardhan told reporters after the meeting.
Asked whether Congress have suggested three names for the candidature, Bardhan said, "we have not been told".
In a bid to evolve a consensus on the issue, Left leaders are scheduled to meet Singh and Gandhi later in the day.
Karunanidhi will also be having a second round of talks with Singh and Gandhi around noon at the Prime Minister's residence.
Meanwhile, a weekly cabinet scheduled on Thursday was deferred till Friday for holding consultation on the presidential election.
Karunanidhi had on Wednesday night, after his meeting with Singh and Gandhi, said that two-three names were under discussion for UPA nominee.
The DMK patriarch had said that he had come here to mediate between Congress and the Left to resolve differences between them. Left have been pitching for External Affairs Minister Pranab Mukherjee for the top post.
Congress has asked leaders of UPA allies to be available in the capital for consultations till June 17 indicating thereby that the formal announcement of the alliance nominee would be made by that day.
The opposition camp also geared up for a fight with NDA leaders suggesting that the formal announcement of Vice President Bhairon Singh Shekhawat's nomination as an independent candidate would be made on June 18.
