Chief Minister C. Joseph Vijay faces a legislative floor test in Chennai as rebel AIADMK lawmakers pledge their support to his government [1].

The shift in loyalty could trigger a formal split within the AIADMK, potentially altering the balance of power in the Tamil Nadu Legislative Assembly. This development intensifies a power struggle between the rebels and the camp of AIADMK leader Edappadi K. Palaniswami [1, 2].

Among those backing the newly sworn-in government are C.V. Shanmugam and S.P. Velumani [1]. These leaders have distanced themselves from Palaniswami, creating a rift in the opposition's ranks as the state prepares for the confidence vote [2].

The political tension has led to a return of resort politics in the region. Reports indicate that the AIADMK has rushed lawmakers to Puducherry in an attempt to prevent further defections to the Vijay administration [3].

To maintain a majority in the 234-seat Assembly, a government must secure at least 118 seats [4]. The support of the AIADMK rebels may provide a critical buffer for the Chief Minister during the upcoming vote [4].

The floor test is scheduled for Wednesday, the day following the reported pledges of support [2]. While the Palaniswami camp has warned of action against those breaking party ranks, the rebels appear committed to the new government [2].

Vijay's administration continues to navigate these shifting alliances as it seeks to solidify its mandate in the legislature [3].

The shift in loyalty could trigger a formal split within the AIADMK.

The defection of high-ranking AIADMK leaders to Chief Minister Vijay's camp suggests a significant erosion of Edappadi K. Palaniswami's authority. By securing support from opposition rebels, Vijay not only stabilizes his own majority but also weakens the primary opposition party's ability to challenge his governance, potentially leading to a permanent fragmentation of the AIADMK.
