DMK on Thursday suspended two key party functionaries, both of whom had joined the party at different points of time after being expelled from the AIADMK.
Party General Secretary K Anbazhagan announced the suspension of V Karuppasamy Pandian, a powerful leader in the party's Tirunelveli West district set-up, and Tiruchendur MLA Anitha R Radhakrishnan.
The two had "violated party discipline and brought disrepute" to it, Anbazhagan said in a statement, adding, they were being suspended from all party posts, including primary membership.
Pandian had joined DMK after being expelled in 2000 by AIADMK supremo Jayalalithaa while Radhakrishnan, also thrown out of the party, joined in 2009.
Radhakrishnan is representing Tiruchendur for a successive term.
