In 2020, former IPS officer K. Annamalai entered politics by joining the Bharatiya Janata Party, quickly emerging as the party's most prominent face in Tamil Nadu. Elevated to state president within a year, Annamalai became known for his aggressive attacks on the ruling DMK, high-profile protests, and extensive grassroots outreach. His statewide yatra further boosted his visibility, transforming him into a major political figure. However, despite generating significant public attention, the BJP struggled to convert momentum into major electoral gains, eventually leading to a leadership change that saw Annamalai replaced as state chief.
