"We can't say forget my past record. Everybody is entitled to judge the candidate on his past record as well as on what he promises to do. His past record is highly questionable, highly debatable, highly controversial," he said.
P. Chidambaram said if BJP as an opposition party had the right to criticise the ruling coalition, Congress too had the right to criticise Narendra Modi.
Congress has been attacking the Gujarat Chief Minister relentlessly over his role during the 2002 post-Godhra riots.
"So we will draw attention to his past record and we will criticise his policies as and when they announce them. I have now not yet heard, a set of policies from either Narendra Modi or the BJP," Chidambaram told newschannel ET Now.
He was responding to a question whether 2014 elections were about Narendra Modi's past or the developmental agenda that he has been talking about.
