Congress MP Karti Chidambaram said K Annamalai, who recently quit the BJP, had joined the party because actor Rajinikanth did not form a political outfit. "Annamalai does not come from the Sangh Parivar...and he is not an ideologue in the Hindutva sense," Chidambaram added. "Annamalai has realised...that the BJP has very limited acceptance and purchase in Tamil Nadu," he stated.
