Dikshit told NDTV that she believes a recent sting operation against Kejriwal's party has ensured that "the self certification of great honesty that was given, is washed out."
"The person who came with a very clean image now has a darkened image. That's all I can say," Ms Dikshit said about Mr Kejriwal, an activist-turned-politician who is contesting the Delhi elections on an anti-corruption plank and is has directly challenged Ms Dikshit in her constituency, New Delhi.
"Opinion polls we feel have no basis. Why should we be scared? We are always confident. We know the reality. You people don't know the reality. You come out with polls because it is your job. But it's certainly not impacting us," Dikshit said.
She said her political opponents lack ideas. "What campaigning are they doing? What ideas are they putting across? Apart from the fact that everybody is trying to fool the people, saying things that are not just incorrect, is there anything substantial that they've said?" she asked.
