The CPI(M) announced it will support Vijay’s Tamilaga Vettri Kazhagam (TVK) to form the Tamil Nadu government through outside support [1].

This move is critical for the stability of the state government, as it provides a path for the TVK to reach a majority and avoid a constitutional vacuum. By offering support from outside the ministry, the CPI(M) seeks to facilitate a functioning government without taking cabinet positions [1, 2].

K. Balakrishnan, a leader of the CPI(M), said the decision was based on the election results. He said that the TVK emerged as the single-largest party and the people’s mandate must be respected [1].

Balakrishnan also noted that the party's primary goal was to maintain local governance. He said the CPI(M) wanted to avoid President’s Rule or Governor’s Rule in the state [1].

Further reinforcing this position, CPI(M) member M.A. Baby said that only Vijay’s TVK has the chance to form a government in Tamil Nadu [2]. This endorsement follows a period of uncertainty regarding the state's leadership and the requirements set by the governor to prove a majority before an oath ceremony can occur [3].

The TVK, led by Vijay, now has a clearer path to power as other parties, including the VCK, have also indicated support [2]. This collective backing aims to ensure that the single-largest party can successfully govern the state without federal intervention.

TVK emerged as the single‑largest party and the people’s mandate must be respected.

The CPI(M)'s decision to provide outside support allows Vijay's TVK to claim a majority without the TVK having to concede ministerial portfolios to a coalition partner. By prioritizing the prevention of President's Rule, the CPI(M) is positioning itself as a stabilizer of the state's democratic mandate while maintaining its political independence from the executive branch.
