The Communist Party of India (Marxist) threatened to withdraw its outside support from Tamil Nadu Chief Minister Joseph Vijay if the AIADMK joins the cabinet.

This tension threatens the stability of a fragile majority in a hung assembly, where the government relies on a delicate balance of partners to maintain power.

The conflict follows a trust vote held on May 13, 2024 [1]. During that session, 25 AIADMK rebel MLAs voted in favor of Vijay [1], contributing to a total of 144 votes secured by the Chief Minister [1].

The Vijay government is approximately 10 days old [1]. While the administration has successfully navigated its initial trust vote, the CPI(M) remains opposed to any formal inclusion of the AIADMK, or its factions, within the cabinet ranks [1].

Party officials said the move is intended to prevent the AIADMK from altering the balance of power. The CPI(M) currently provides outside support to the administration, but the party is now signaling that such support is conditional on the exclusion of its political rivals [1].

Chief Minister Vijay must now balance the need for a broader cabinet base with the demand for ideological purity from the CPI(M). The potential exit of the communist party could jeopardize the government's numerical advantage in the assembly, especially given the reliance on rebel members from other factions [1].

The CPI(M) threatened to withdraw its outside support from Tamil Nadu Chief Minister Joseph Vijay if the AIADMK joins the cabinet.

The ultimatum from the CPI(M) highlights the volatility of the current Tamil Nadu administration. By leveraging its outside support, the CPI(M) is attempting to dictate the composition of the cabinet to ensure the AIADMK does not regain institutional influence. If Chief Minister Vijay chooses to bring AIADMK factions into the fold to solidify his majority, he risks a collapse of the coalition, potentially triggering another leadership crisis in the state.
