Tamil Nadu's ruling AIADMK will fight for its former chief minister J Jayalalithaa's seat under a new name - two in fact. Party chief VK Sasikala's faction will call itself AIADMK Amma, and rival O Panneerselvam's group will go by the name AIADMK Puratchi Thalaivi Amma. Both factions will also fight under new symbols after the Election Commission said yesterday that neither can use the AIADMK's name and "two leaves" symbol in the contest for RK Nagar in Chennai. "Amma" or mother is the name given to Jayalalithaa by thousands of her supporters. Superstar Rajinikanth added another interesting twist to the by-poll battle by announcing on Twitter that he supported "no one".
