Jayalalithaa is fondly addressed as "Amma," meaning mother in Tamil, by her supporters.
AIADMK Coordinator and Deputy Chief Minister, O Panneerselvam and party Co-Coordinator and Chief Minister, K Palaniswami led a silent procession of party workers from Anna Salai to Jayalalithaa's mausoleum on Marina beach in Chennai.
Most party workers, including the two leaders and many other ministers, were clad in black shirts.
Scores of party supporters also turned up at the mausoleum to pay tributes to her.
Jayalalithaa, admitted to a corporate hospital here in September 2016, breathed her last this day last year, after 75 days of hospitalisation.
