At a session of a two-day programme 'Agenda' organised by Aaj Tak news channel, the science and technology Minister said that in democracy, if a person is having any evidence of corruption against someone, then it is his responsibility to make it public.
"You ask Digvijay Singh about this. This is dangerous for democracy. If you have evidence against someone, then it is your responsibility to produce it in front of the public," Sibal said.
He was asked to comment on Singh's recent statement that to has evidence of graft against some BJP leaders but is not willing to come out with it.
"Not only me. There were lot of things, which came out during the NDA regime. But did Congress party ever use that. We will never use this... If I say, I do not have it (evidence against kin of L K Advani and Atal Bihari Vajpayee), then it is not correct," Singh had said during a TV interview recently.
Sibal along with BJP's Leader of Opposition in Rajya Sabha Arun Jaitley and CPI(M)'s senior leader Sitaram Yechury also fielded questions on future leadership of the country during next general elections.
Both Sibal and Jaitely refused to comment on future leadership of their parties and said that it will be decided at an appropriate time.
Asked to comment on Rahul Gandhi's candidature for the post of Prime Minister from Congress, Sibal said, "First I will like to say that please leave it to the Congress party to decide what will happen in 2014. Please wait till 2014."
He insisted that future leadership of the country will come from Congress party only.
"It is sure that all leaders will emerge from Congress party only and Congress leadership will present itself in front of you," Sibal said.
Asked to comment on a recent statement by senior BJP leader Sushma Swaraj that Gujarat Chief Minister Narendra Modi has the ability to become Prime Minister, Jaitley said the party has several talented leaders and Modi has proven his skills as one of them.
"We have several talented leaders. Modi has established his capability by winning elections and with good administration. We have a system to decide the leadership of BJP and NDA, and we will follow that," he said.
Asked to comment on a general perception against Modi that he divides the nation, Jaitley said, "For every leader there can be praise and opposition together. His (Modi's) administrative and political skills are known to every one."
