He was 58.
Ilamvazhuthi, known for his oratory skills took on the AIADMK government single-handedly as the other DMK member, party patriarch, M Karunanidhi had resigned from his membership after winning from Harbour constituency in 1991.
During 1991-96, the AIADMK had a thumping majority winning 164 out of 234 seats; while its ally Congress had bagged 60 seats in the 1991 Assembly election following the assassination of former Prime Minsiter Rajiv Gandhi in 1991.
After spending decades in DMK, Ilamvazhuthi joined the AIADMK in 2013 following differences with M K Stalin.
Stalin recalled that Ilamvazhuthi had worked alongside him in the DMK for decades and nurtured the growth of party's youth wing.
"His death is shocking and I am grieved. We will never forget the love he had for Kalaignar though he wavered due to political or other reasons," Stalin said.
In 2003, during the AIADMK regime, Ilamvazhuthi, who had held several DMK party posts was sentenced to 30-day imprisonment for breach of privilege by Assembly Speaker and he was later released on the directions of the Madras High Court.
