Accompanied by senior party leader and Harbour constituency MLA PK Sekar Babu, Stalin filed his nomination papers at Ayanavaram.
The DMK chief has been representing the constituency since 2011 and is seeking another term, even as his party is keen to capture power by defeating the ruling AIADMK which has been in the ruling saddle for the last ten years.
