Joseph Vijay Chandrasekhar, chief of the Tamil Nadu party TVK, took the oath of office as Chief Minister of Tamil Nadu on Sunday [1].

The transition marks a historic shift in the region's political landscape. For the first time since 1967 [2], a leader from outside the DMK and AIADMK formations has headed the state government [2].

The swearing-in ceremony took place at Chennai's Jawaharlal Nehru Indoor Stadium [1]. Following the ceremony, Vijay officially assumed charge at the Tamil Nadu State Secretariat [1].

This political upheaval follows an election where the TVK secured enough members of the legislative assembly to form a government [3]. The shift ends nearly six decades of dominance by the DMK and AIADMK [4].

The Tamil Nadu Legislative Assembly consists of 234 members [5]. To secure a majority, a party or coalition requires 118 MLAs [5]. Currently, the TVK tally stands at 117 MLAs [5].

Prime Minister Narendra Modi and other prominent figures, including Kamal Haasan and Sathyaraj, sent their wishes to the new chief minister [6].

Ending nearly six decades of DMK-AIADMK dominance

The ascent of Joseph Vijay Chandrasekhar represents a fundamental break in the bipolar political structure of Tamil Nadu. By displacing the long-standing DMK and AIADMK hegemony, the TVK has introduced a third force into the state's governance. However, with 117 MLAs in a 234-member house [5], the administration sits exactly one seat short of an absolute majority [5], suggesting that the new government's stability may depend on strategic alliances, or the support of independent members.
