Yadav went to the residence of Badal, son of Punjab Chief Minister Parkash Singh Badal, and is understood to have discussed the possibility of the two parties joining forces in the event of formation of a non-Congress government, sources said.
During the 30-minute meeting, the SP chief is believed to have talked about the senior Badal getting a larger role at national level, the sources said.
Sukhbir Badal, who is Punjab Deputy Chief Minister, refused to say anything on the meeting.
However, party spokesman B S Ramoowalia, who was present during the meeting, said Yadav sought Akali support to "save the nation from the economic crisis due to the policies of the Congress-led government at the Centre, especially with regard to recent decision of allowing FDI in multi-brand retail."
Hours later, Yadav was asked by reporters whether he had met Badal as part of efforts to explore the possibility of forming a third front.
"I have never said the third front is being made. I said that it will be formed after elections. Any (political) equation will take place after election only," he responded.
