Tamil Nadu election 2026: A look at what defined the outgoing 16th Assembly of TN

The tenure of the 16^th Tamil Nadu Legislative Assembly, which began on May 11, 2021, was marked by several distinctive developments including sustained confrontation between the Governor and the State government, historic resolutions, and notable administrative innovations.

The House was constituted following the DMK’s return to power with a clear majority after a gap of 25 years. While the party had formed the government in 2006 with 96 members and outside support from allies, including the Congress and PMK, the 2021 mandate was decisive. The DMK secured 133 seats, comfortably crossing the majority mark of 118, while overall, its Secular Progressive Alliance bagged 159 seats.
