With the exit polls painting a completely mixed picture, J Jayalalithaa managed to break the anti-incumbency jinx and register a comfortable win by breaking a three-decade long trend in the Tamil Nadu Assembly elections.
The AIADMK bagged 134 seats - 40.8% of the total votes polled (1,76,11,000) votes), according to data collated by the Election Commission.
However, the DMK and its allies - including Congress - gave a tough fight and emerged a strong opposition winning 95 seats and leading in two. The DMK bagged 89, while the Indian Union Muslim League bagged 1 seat.
After registering a historic win, Jayalalithaa thanked the people of the state for their support, which helped her retain power. "I am overwhelmed by the resounding victory the people of Tamil Nadu have given us. My party and I are indebted to the people of Tamil Nadu for giving this historic victory," she said.
While the AIADMK chief set to retain power in Tamil Nadu, DMK chief M Karunanidhi broke his own record by registering his 13th consecutive win in the Tiruvarur constituency - by margin of over 60,000 votes over AIADMK's ANR Paneerselvam.
Additionally, his son MK Stalin won from Kolathur constituency in Tamil Nadu with a margin of over 12,000 votes.
Polling in two constituencies has been postponed to 23 May.
