Ramachandran has been removed from post and his primary membership has been withdrawn for "going against" the party's policies and "bringing down" its reputation, Sasikala said in a statement.
The removal comes after Ramachandran reportedly offered support to caretaker chief minister O Panneerselvam who has raised the banner of revolt against Sasikala.
In another statement, the 62-year-old leader said VVR Raj Sathyan will replace Ramachandran and appealed cadres to offer him their support.
Panneerselvam yesterday dropped a bombshell by saying he was "forced" to resign on Sunday to make way for Sasikala and hinted that he may withdraw his resignation if people of Tamil Nadu and party cadres so desired.
