What does an MLA do in Tamil Nadu?

An MLA (Member of the Legislative Assembly) represents one of the 234 assembly constituencies. MLAs vote on state legislation, state budget, and policy. They raise constituency issues in the assembly. They are also the primary point of contact for constituency-level development — schools, roads, hospitals, drinking water. MPLADS (Member of Parliament Local Area Development Scheme equivalents at state level) funds are channelled through MLAs for local projects.

How does Tamil Nadu elect its government?

Tamil Nadu holds state assembly elections every 5 years using a first-past-the-post system. Each of the 234 constituencies elects one MLA — the candidate with the most votes wins (no minimum threshold required). Voters cast one vote for their preferred candidate. The party or alliance winning 118+ seats forms the government. Last election: 2026.

How is Tamil Nadu's government different from the central (national) government?

India has two levels of elected government: Central (national) government in New Delhi, and State governments in each of 28 states. Tamil Nadu's state government handles: education, public health, police, state roads, water supply, agriculture. The central government handles: defence, foreign affairs, income tax, railways, national highways. Tamil Nadu votes separately for its state assembly (like 2026) and for the Lok Sabha (national parliament, last held in 2024).

What is the Tamil Nadu assembly term? When is the next election?

A Tamil Nadu Legislative Assembly serves a 5-year term unless dissolved earlier. The 2026 assembly election resulted in a new government. The next scheduled election would be in 2031, unless the assembly is dissolved early by the Governor on the CM's advice or under President's Rule.

Can non-resident Indians (NRIs) or Tamil diaspora vote in Tamil Nadu elections?

Indian citizens living abroad (NRIs) are eligible to vote in Indian elections if they are registered on the electoral roll of their home constituency. As of 2026, overseas voting requires physical presence in India on election day — postal voting for NRIs is under discussion in India's Election Commission but not yet implemented. Tamil diaspora citizens of other countries (e.g., Sri Lankan Tamils with foreign citizenship) are not eligible to vote in Indian elections.
