Ms J. Jayalalithaa (left), Chief Minister of the southern Indian state of Tamil Nadu and party leader of the All India Anna Dravida Munnetra Kazhagam (AIADMK), arriving to cast her vote at a polling station in Chennai yesterday in state assembly elections. Tamil Nadu was one of five states holding assembly elections yesterday. By the time polls closed at 6pm local time, 69.2 per cent of eligible voters had cast their votes in Tamil Nadu - a drop from the 78.3 per cent voting recorded in 2011, NDTV reported. The low turnout could be a result of bad weather, which slowed down the polling, especially in the southern part of the state. Exit poll results show a close fight between AIADMK and the Dravida Munnetra Kazhagam (DMK), led by Mr M. Karunanidhi. Political power in Tamil Nadu has alternated between the AIADMK and DMK every five years over the last three decades.
