Supporting BJP's decision to walkout of the JPC meeting on 2G scam, JD-U today said Congress members cannot deny the opposition party's demand to conduct a debate on the list of witnesses in the case.        

Talking to reporters in New Delhi,  JD-U chief Sharad Yadav also said that boycotts and debates are part of Parliamentary process including JPC to ensure result-oriented functioning of these bodies.        

"Yashwant Sinha told me that he sought a discussion on the list of witnesses in the 2G case. But they (Congress members) refused to give time for this. How can they refuse the demand for a debate? If you don't conduct debates how do you plan to get any result in the 2G case," Yadav said.
