The 234-seat Assembly election in Tamil Nadu will see the ruling Dravida Munnetra Kazhagam (DMK), led by Chief Minister M K Stalin, take on the opposition All India Anna Dravida Munnetra Kazhagam (AIADMK) and a resurgent BJP-led alliance. The campaign is centred around issues such as welfare schemes, law and order, and the broader debate between Dravidian political identity and national integration narratives. While the DMK government is highlighting its record on industrial growth and social justice, the opposition has targeted it over allegations of corruption and concerns about power shortages.
