Attacking BJP MlAs for walking out of the Aseembly, Transport Minister Gopal Rai said, “Today, no marshals were used to escort them out of the House, but they left voluntarily. That’s because they cannot speak for the cause of safety of women.”Defending his Government’s resolution to form a Commission of Enquiry, Rai said the move is within the purview of the constitution. “Right now, we are fighting within the purview of the constitution for the rights of the women, but if the safety and security of women in Delhi is under threat, we have the will and strength to change the Constitution as well,” he said.
