Vijay, leader of the Tamil Nadu party TVK, was sworn in as the chief minister of Tamil Nadu on Sunday morning [2].

The appointment marks a significant shift in the state's political landscape as a new party takes control of the government. This transition occurs amid intense speculation regarding the stability of the new administration and the potential for unprecedented alliances among established political rivals.

Vijay's party emerged as the single largest party in the recent elections [2]. To secure the government, he received backing from a coalition of smaller parties, including the CPI, CPI(M), VCK, and IUML [2]. The swearing-in ceremony was met with loud cheers from his supporters [2].

Despite the official appointment, reports indicated a period of high political tension during the government formation process. There was significant buzz that the DMK and AIADMK — two Dravidian parties that have not formed a coalition for over 50 years [1] — might join forces to prevent Vijay from taking power [1].

Such a pact between the DMK and AIADMK would have represented a historic departure from their long-standing rivalry. However, the current government formation indicates that the support from smaller parties was sufficient for Vijay to assume the office of chief minister [2].

Vijay took oath as Tamil Nadu chief minister after his party received support from smaller parties.

The ascent of Vijay and the TVK suggests a disruption of the traditional bipolar political order in Tamil Nadu. While the DMK and AIADMK have historically dominated the state, the emergence of a new single largest party forces established players to reconsider their alliances, potentially leading to a more fragmented or multi-polar legislative environment.
