He has also lampooned the PM and his predecessor Manmohan Singh through pictures to drive home his point.
"The party which had sought votes in the general election on the issue of corruption and black money during its five month tenure has come out with only three names which also they are not confirming," Kumar, a known rival of Prime Minister Modi, said reacting to the Centre's affidavit before the Supreme Court in the black money case.
"Kya is desh mein kewal teen logo ke pass kala dhan hain (do only three persons in the country have blackmoney)?" he said in his sarcastic comment. "Everyday a new issue of BJP falsehood and fraud comes before people...BJP has become synonymous with 'Bhrasht Jhooti Party'," the senior JD(U) leader, who led his party's snapping of ties with BJP last year over elevation of Modi, said.
Kumar's hard-hitting comments came on a day when he is meeting JD(U) MPs, MLAs and office bearers on his 16-day "Samparak yatra" starting from November 13 ahead of crucial Assembly poll next year.
