New Delhi, Nov 01 (ANI): The Bharatiya Janata Party on Friday hit back at Communications and IT Minister Kapil Sibal for challenging his party's prime ministerial candidate Narendra Modi for a debate. BJP leader Ravi Shankar Prasad asked Sibal to debate with him first on the questions the Congress party has been running away from. Talking to mediapersons in New Delhi, he also said that Sibal had said that there was zero loss in 2G scam, but this was the same scam which lowered country’s image worldwide.
