He said that the central committee would take a final call if the state committee took a favourable decision.
"It was not the agenda of the plenum to discuss the matter. As far as election tactics are concerned, the state committees will discuss and take the decision on the basis of the concrete situation. Once the state committees have taken the decision, they will send us (central committee & politburo) the proposal and we will take the final call," Yechury told reporters on the sidelines of the concluding session.
Yechury on Monday had said the decision and discussion in this regard would be taken up in the month of January.
