"Mamata Banerjee had come to me yesterday. However, I will not disclose what we discussed," said Yadav, whose party's support will be crucial for election of the next President.
He said he would reciprocate Banerjee's gesture by discussing the issue of presidenial elections with her before his party decides on whom to support.
Yadav's remarks came a day after Banerjee said she would talk to the SP leader again after meeting Congress President Sonia Gandhi on Wednesday evening on the issue of the United Progressive Alliance's presidential candidate.
On Jaswant Singh's meeting with him on Tuesday, Yadav said the BJP leader had discussed the President and vice president elections.
Meanwhile, sources in SP said the party leadership was inclined to support the candidature of Finance Minister Pranab Mukherjee for the next President.
Yadav is understood to have told his party's members of Parliament recently that he personally would prefer Mukherjee but a final decision could only be taken after Congress officially comes up with a name.
