The Tamil Nadu government issued a government order on 12 May 2026 appointing astrologer Rickey Radhan Pandit Vettrivel as the Officer on Special Duty to Chief Minister C. Joseph Vijay. The temporary position was designed to handle political coordination and liaison tasks directly within the Chief Minister’s Office. Following intense public backlash and criticism from alliance partners regarding scientific temper and governance secularism, the Tamilaga Vettri Kazhagam government revoked the appointment on 13 May 2026. Vettrivel, an expert in Vedic astrology, had previously advised the Chief Minister on the timing for his swearing-in ceremony on 10 May 2026.
