"We will make corruption a major issue in the polls," Yadav told reporters here today.
He alleged that the builders and land mafia in the state were indulging in large scale corruption and government jobs were not being provided on merit basis.
When asked regarding reports that Congress was thinking about changing its Chief Minister in the state, Yadav said changing or not changing the Chief Minister would not grant any relief to the ruling outfit "which has lost its credibility among the people for its anti-people policies."
AAP put up a poor show, failing to win even a single seat, in Haryana in the recently concluded Lok Sabha elections.
Yadav himself was defeated from the Gurgaon parliamentary seat.
