Both Lok Sabha and Rajya witnessed uproar and the Lower House had to be adjourned briefly as the opposition sought to corner the government over the issue, which was a major poll plank of BJP.
"100 days are over, where is the black money?" chanted members of Trinamool Congress, Congress, RJD, Samajwadi Party and AAP, who stormed the Well of the Lok Sabha, minutes after it assembled for the day.
The House had to be adjourned for 40 minutes but uproar continued when it re-assembled at noon for Zero Hour.
The Rajya Sabha also saw uproarious scenes over the issue, with members from JD-U, Samajwadi Party and TMC on their feet when the House assembled for the day.
They kept shouting slogans and waving papers attacking the government on the black money issue.
By the evening, government sources said a discussion on the issue could be taken up tomorrow.
