The group said "Kannadiga Rajini" should stay away from Tamil politics.
One of India's biggest stars, Rajinikanth is adored by his millions of fans. "I'm sure he would do lots of good things".
To a question on whether Rajinikanth will join the BJP, Shah said only the actor has to decide that.
Last week brought a surprise for Rajinikanth's fans when addressing an event in Chennai, he said, "Some of my fans urged me to join politics and it's not bad to enter politics, but making money out of this is bad". Amid protests from a few Tamil groups, which are disapproving the Kannada-born's political entry in TN, some reports suggest that Rajini would meet PM Narendra Modi later week.
The actor had, however, last week asserted his Tamil identity, saying his native place was a village in Krishnagiri district in Tamil Nadu.
Considering the actor's influence on fans, Tamil politics could see a new alignment if he joins politics. I have lived and grown with you. Let him tell us where he stands on issues of the common people, only then can he enter politics. You have been truly loving and welcoming and made me a true Tamilian. Asked about it, Gadkari said he is neither an authority nor a decision maker and it is only the party president and party parliamentary board that will take a decision in the matter.
The radical pro-Tamil group stepped a stir outside Rajinikanth's residence at Poes Garden in Chennai, shouting slogans against the actor. He had also added that he is "a pure Tamil" and that he has been in Tamil Nadu for more than 40 years.
"Even God can't save Tamil Nadu" if AIADMK was elected again, he said.
