"The test is yet to be complete. The time has come now for decisions. My heartfelt thanks to every worker, supporter, leader, office bearer and well-wishers of the Samajwadi Party and alliance for being alert and active, day and night, at counting centers," Yadav tweeted, referring to the controversy over allegations that some elements tried to take away electronic voting machines, or EVMs, from a strong room in UP.

"Sepoys of democracy return only with a certificate of victory," Yadav said.
