"If she cannot raise her voice on behalf of Dalits inside the House, there is no purpose of sitting inside the house," Mr Mishra said. On Tuesday, during her speech to highlight what she called frequent attacks on Dalits in Uttar Pradesh, was interrupted multiple times.
"She spoke for 2 minutes. She was interrupted 62 times by the treasury benches, ministers," he said. Mayawati had angrily walked out of Rajya Sabha, saying she would resign.
Her resignation letter was accepted today, after it was presented in the correct format.
Her move has found support from Lalu Yadav, who commands huge support among the Dalits and backward castes in Bihar. "Today would be remembered as a black day in the history when a highly respected Dalit leader was not allowed to raise the voice of poor in the Rajya Sabha," the Rashtriya Janata Dal leader said.
He also offered to field Mayawati from Bihar. Regarding the offer, Mr Mishra said, "She has already thanked him. But if she had to accept any offer, she would not have resigned... She is not one of them."
Mayawati has only 18 legislators in the 403-member house in Uttar Pradesh - a number that would be far from sufficient to ensure her a seat in the Upper House. Her move to walk out of Rajya Sabha on the Dalit issue is seen as a measure to recapture her party's slipping core voter base. Mayawati's Bahujan Samaj Party has been out of power for two terms - the last assembly election held earlier this year had seen the BJP win a resounding victory in the state. The party has won 300 of the state's 403 seats - a feat that could not have been possible without significant support from the Dalits.
