Sibal in an interview to Reuters, questioned Modi's presence on cyberspace and said that he was bombarding the cyberspace with misinformation.
"Private army was employed by Modi to disturb cyber space in his favour," he said.
Calling Modi a bubble he said that all bubbles burst, this bubble will also burst. "I am sure it will burst before elections," he said. He also lashed out at Modi for selling Gujarat's model of growth.
"The number of statements made by this gentleman is far from the truth. What is Gujarat's model of growth? You cannot sell a product which you don't have," he said.

On asking him about Narendra Modi's rise on the political front he said: "The faster a person rises, the faster he falls down.' He added that Modi was just like another political contender for him and that there was nothing special about it.
Sibal, however refused to comment on Rahul Gandhi as PM. "That's not for me to decide, I do not make any personal comment. These are issues which the party has to decide," he said.
