No one's more opportunistic than 'chacha': Tejashwi on Bihar CM
Yadav's remarks on Sunday came after JD(U) struck a deal with BJP on seat sharing for upcoming Lok Sabha election.
JD(U) and BJP will contest on 17 seats each, and LJP on six.
Chacha was abused but stayed with NDA: Yadav
Yadav, who is a former minister of Bihar government, said, "Despite being abused, if my chacha can continue with the NDA, then is it fair to dub the opposition as opportunists."
He called the deal a knee-jerk reaction of the NDA after Rashtriya Lok Samata Party (RLSP) quit NDA and joined hands with the grand alliance.
Upendra Kushwaha's exit rattled the NDA, Yadav claimed.
Earlier, PM Modi said grand alliance was deal for power
Yadav's statement was also an apparent retort to Prime Minister Narendra Modi, who had said the mahagathbandhan was about political survival and not ideological support.
"This alliance is for personal ambitions and not for people's aspirations," he said on Sunday.
Notably, Kushwaha also didn't let the opportunity of taking a dig at PM Modi pass and said the 56-inch chest shrunk to 36 inches.
