Pattali Makkal Katchi (PMK) faction led by S Ramadoss and All India Puratchi Thalaivar Makkal Munnetra Kazhagam (AIPTMMK), founded by VK Sasikala, will jointly contest all 234 Tamil Nadu seats in April. Ramadoss's estranged son had aligned the main PMK faction with NDA, while Sasikala was earlier sidelined from AIADMK. "The alliance will...remove...symbols of betrayal in Tamil Nadu," they said.
