"I have complete conviction that Congress will support the Bill the same way it did in Lok Sabha, or else the minority women will not spare them," Union Minister Giriraj Singh told ANI on Monday.
Union Minister Narendra Singh Tomar echoed the same conviction.
"I believe all our office-bearers will talk to all parties, and all parties will understand the problem faced by our aggrieved sisters. This bill, I believe, will be passed in the Rajya Sabha," he said.
The BJP has issued a three-line whip to its MPs to be present in Parliament to ensure passage of the bill.
Commentators say noisy scenes are expected in the Rajya Sabha on Wednesday.
