Prime Minister Narendra Modi and BJP national president Amit Shah have directed party leaders to toe the party line while speaking at public forums, he said.
"I think the Bihar Assembly polls will be a cakewalk for us and an one-sided affair," Hussain said.
"Nobody wants the return of jungle raj in Bihar," he said and took a dig at the JD(U)-RJD merger talks saying former chief minister Nitish Kumar and RJD supremo Lalu Prasad were desperate for the merger to revive their fading hope of another term in power.
