The Tamil Nadu unit of the Bharatiya Janata Party (BJP) faced a notable setback as Vice President Karu Nagarajan and Secretary Sumathi Venkatesh resigned shortly after K Annamalai's departure from the party. Nagarajan announced his intention to join Annamalai's newly formed political outfit, praising Annamalai's leadership and his ability to expand the BJP's influence across Tamil Nadu. He emphasized Annamalai's unique capability to resonate with the electorate, even without holding an official position for the past 18 months. Nagarajan also highlighted Annamalai's vision for political reform, focusing on youth opportunities and the elimination of dynastic politics. Meanwhile, Venkatesh shared her resignation on social media, expressing her pride in serving the BJP while acknowledging her deep inspiration from Prime Minister Narendra Modi's leadership. Annamalai's exit marks the end of his six-year association with the BJP, during which he had expressed differences with the party's top leadership regarding its direction in Tamil Nadu.
