C. Joseph Vijay, president of Tamilaga Vettri Kazhagam (TVK), was sworn in as the 15th Chief Minister of Tamil Nadu.
The swearing-in ceremony was held at Jawaharlal Nehru Indoor Stadium in Chennai.
Governor Rajendra Vishwanath Arlekar administered the oath of office and secrecy to the new Chief Minister.
Nine ministers were sworn in along with him.
The Governor appointed the Chief Minister under Article 164 of the Constitution.
The Governor also directed Vijay to seek a vote of confidence in the Assembly on or before 13 May 2026.
The new Cabinet marked the first time in five decades that Tamil Nadu was ruled by neither the All-India Anna Dravida Munnetra Kazhagam (AIADMK) nor the Dravida Munnetra Kazhagam (DMK).
Since 1950, Tamil Nadu has had 14 Chief Ministers before Vijay, and he became the 9th Chief minister after the State was renamed Tamil Nadu in 1969.
V. R. Nedunchezhiyan served twice as Acting Chief Minister after the deaths of C. N. Annadurai in 1969 and M. G. Ramachandran in 1987.
K. Kamaraj of the Indian National Congress served as Chief Minister for the longest period from 1954 to 1963.
