Paramakudi-based party functionary M A Muniyasami has been appointed in the place of Manikandan, a party release said.
Jayalalithaa said Manikandan would continue to function as party's medical wing deputy secretary, according to the release.
Earlier this month, Jayalalithaa had restructured the party's apex body 'Thalamai Kazhagam' and named several new state office-bearers.
In today's exercise, she also appointed several new office bearers for the Ramanathapuram district unit, easing out the incumbents from their responsibilities.
