The Congress on Tuesday alleged that two different kinds of Rs 500 and Rs 2,000 notes were printed post demonetisation, "jeopardising the credibility" of Indian currency, and demanded that Prime Minister Narendra Modi clear the air on the issue.
The opposition party, which disrupted proceedings in the Rajya Sabha over the issue forcing its adjournment for the day, said the "discrepancies" in the printing of the new high denomination notes were in terms of their size, design and other features.
It asked PM Modi and Finance Minister Arun Jaitley to explain as the issue "raises questions over the country's financial structure".
Senior Congress leader Kapil Sibal, who flagged the issue in the Rajya Sabha earlier in the day calling it the "biggest scam of the century", said the opposition party would keep raising it in Parliament until the government explains its stand on the issue.
"Today we have discovered why the government took the demonetization decision. The RBI prints two types of currency notes. These are of different size and different design... how is it possible?" questioned Congress leader Kapil Sibal, waving a placard with the two notes.
Leader of the Opposition in the Rajya Sabha Ghulam Nabi Azad said that one kind of note was "for the party [Bharatiya Janata Party]” and the other "for the government”. "We never printed two kinds of notes, one for the party and one for the government - there are two kinds of Rs 500 notes and two kinds of Rs 2,000 notes.”
The government hit back by accusing the Congress and the Trinamool Congress of raising "frivolous" issues and creating confusion in the country by making such claims.
Finance Minister Arun Jaitley, however, accused the Congress of making irresponsible statements, and claimed that the party was misuing the Zero Hour. He later said he would verify the authenticity of the notes. "Given such a big print run there can be an odd case of a currency note being slightly bigger or not.”
The Rajya Sabha was adjourned following the incident.
