"If he (Rahul) wants to know about RSS, left him attend functions and wear uniform and sit in RSS shakhas," Radhakrishnan said.
Replying to a specific question on Gandhi's criticism against RSS, Radhakrishnan, here to attend a marriage function, said it was ridiculous that the Congress leader who was at large for 55 days when Parliament was in session, was talking about democracy.
"He has no right to talk about RSS," he added.
On former Prime Minister Manmohan Singh meeting Prime Minister Narendra Modi, Radhakrishnan said they might have discussed schemes and policies for the development of the nation and not to take lessons on economy, as made out by different political parties and critics.
On criticism by CPI leader D Pandian that Modi going on foreign trips would only help big corporates, he said the purpose of these visits was to strengthen relationship with countries and evolve schemes for India's future growth.
