2016 Tamil Nadu Legislative Assembly election
The Tamil Nadu Legislative Assembly election was held on 16 May 2016 for the 232 seats of the Legislative Assembly in the state of Tamil Nadu in India. AIADMK under J. Jayalalithaa won the elections and became the first ruling party to be re-elected in Tamil Nadu since 1984, though with a reduced majority. DMK won half of the seats it contested but its allies performed poorly; notably, the Indian National Congress won 16% of the seats they contested and the alliance lost due to its poor performance. The votes were counted on 19 May 2016. In the previous election in 2011, AIADMK, under the leadership of Jayalalithaa, won a simple majority and formed the government, while DMDK chief Vijayakanth served as the Leader of Opposition until January 2016. This was the last election that J. Jayalalithaa and M. Karunanidhi contested, as they both died in 2016 and 2018 respectively.

On 12 February 2016, Election Commission of India announced that 17 assembly constituencies in Tamil Nadu will have Voter-verified paper audit trail machines attached along with EVMs. Voter-verified paper audit trail machines will be in place in 4,000 booths.

Campaign to vote
To ensure that the electorate exercise their right to vote, the Election Commission of India launched their own campaign in Tamil Nadu. The Chief Electoral Officer for the Tamil Nadu assembly elections, Rajesh Lakhoni, utilised social media platforms by creating memes and tweets themed around films, which have a huge reach in Tamil Nadu. Additionally, the Election Commission also recruited media personalities Suriya, Ashwin and Karthik, whose campaigning videos were filmed and shared on social media. The Election Commission also partnered with Twitter, for the first time in India, to boost its #TN100Percent hashtag campaign. Twitter users who have made use of the hashtag will be reminded to vote on the day of voting. Twitter and Facebook collaborated with ECI in its awareness campaign on striving for 100 per cent voting in the polls.Parties and Alliances

Controversies
On 3 May, News 7 and Dinamalar released an opinion poll giving an edge for DMK over AIADMK. But some editions of Dinamalar carried a statement on the first page distancing itself from the surveys. In an instance VVPAT was helpful in resolving an issue pertaining to a tally of votes in Kancheepuram as the number of votes entered in the Form 17C of a polling booth and the total number of votes recorded in the EVM control unit of that booth did not tally.Cash for votes
Wide spread allegations of parties bribing voters with cash were raised and the Election commission responded by increasing the number of flying squads to conduct raids and prevent distribution of cash for votes. First time in the Indian history Rs 570 crores of three containers captured in Tirupur, no one claimed for that money at the first day. Later SBI claimed that money. Many parties like CPI, CPI, VCK, MDMK, PMK, wanted clear information about that money.Postponement of polls
The Election Commission postponed the polls in Aravakurichi and Thanjavur constituencies due to reports of distribution of huge sums of money and alcohol to voters. The polling was initially postponed to 13 June, despite the Governor of Tamil Nadu requesting that it should happen before 1 June. The date was subsequently amended to November.By-Election
