Samajwadi Party leader Amar Singh had talks with External Affairs Minister Pranab Mukherjee as the Congress searches for new allies to cobble up a majority to form the next government.
The talks between the two took place close on the heels of the AICC General Secretary Digvijay Singh seeking to break the ice with the SP General Secretary by calling him up.
Highly placed Congress sources dismissed speculation that there was any talk of portfolios at the meeting.
The refrain in the Congress camp is that ministerial portfolios could only be discussed when the results are out.
Amar Singh said SP's long-term relationship would depend on what the party got after "bargaining", which would be based on the number of seats SP secures.
"Congress will talk to us if we have the numbers," Singh said.
