"Everyone should realise that Bills are passed and laws are enacted only in the Parliament and not on Ramlila Maidan," he said without elaborating further.
He, however, said that both Kejriwal and BJP’s prime ministerial nominee Narendra Modi were "big megalomaniacs with a strong dictatorial streak."
"I am saying this as I know that both of them like to listen to only to their voices and do not pay heed to anyone else," Digvijay said.
"It was because of this streak that Kejriwal drove away many people including Narmada Bachao Andolan leader Medha Patkar," he added.
Asked if Congress vice-president Rahul Gandhi would be named as the party's prime ministerial nominee on January 17, he said, "Personally, I am strongly opposed to naming prime ministers or chief ministers before the polls."
About Priyanka attending a Congress meeting in New Delhi on Tuesday, Digvijay said that she was looking after the party's media work for the 2014 Lok Sabha elections.
She also takes a keen interest in party affairs in Rae Bareli and Amethi, he said. On Congress' defeat in November 25 assembly elections in Madhya Pradesh, he conceded that the macro-management of the BJP was much better than that of his party in the state.
