AIADMK top leader Edapaddi K Palaniswami (EPS) on Wednesday expelled O panneerselvam's sons and 16 other supporters of the ousted leader from the party.
Raveendranath, the party's Lok Sabha member from Theni constituency and Jeyapradeep, both sons of Panneerselvam and a former Minister, Vellamandi N Natarajan were expelled.
Former legislators and MPs were among 15 others who were expelled from the party's primary membership.
In a party release, Palaniswami said the move is a disciplinary action and all the 18 of them have acted against party interests, principles and brought disrepute to the organisation.
Earlier today, EPS announced the appointment of two senior leaders as deputy general secretaries of the party.
Announcing the appointments of various functionaries for the first time after being elected as AIADMK's interim general secretary, he urged the party workers to extend their cooperation to the new functionaries.
