"The BJP alleged that the opposition has called a Bharat Bandh, but the fact is that the BJP itself has done a Bharat Bandh by demonetising high currency notes," Mayawati told the media.
She said there was no division within the opposition ranks.
"There is no rift in the opposition parties over demonetisation. The entire opposition is united," the former Uttar Pradesh Chief Minister said.
She said the opposition had been demanding answers from Prime Minister Narendra Modi over the November 8 demonetisation that has caused a cash chaos across the country.
"We saw Modiji came to the Rajya Sabha before lunch but skipped the next session because he knew the opposition would demand answers from him," she said. "Why is he skipping Parliament?"
"We heard Modiji speak in Kushinagar, where he accused the opposition of supporting black money and corruption," she said.
"Our party is concerned about the poor implementation of the demonetisation, which has made life of the poor miserable in the last 20 days."
The opposition parties had last week said that November 28 will be marked by nation-wide strike against Narendra Modi government's decision to scrap Rs 500 and Rs 1,000 currency notes on November 8.
