Chennai: Actress-turned-politician Khushboo Sundar on Monday announced her exit from the DMK, a party with which she has been associated since 2010.
"Gave my 100 percent for party, still didn't get recognition," Khushboo said in a statement.
"I'm quitting all my association with DMK and I'm no longer associated with the party. I quit my membership with DMK with a heavy heart," she added.
Khushboo, who joined DMK on May 15, 2010 when the party was ruling Tamil Nadu, said she has no plans of joining any other party.
"I am not jumping into any other party. So stop assumptions and hold back your horses friends. Need some time alone with family (sic)," she posted on her Twitter page, minutes after quitting.
Khushboo is known for films like "Chinna Thambi", "Vetri Vizha" and "Nattamai".
In her resignation letter addressed to DMK president M. Karunanidhi - copies of which were distributed to the media and also on the social media - Khushboo said she had joined the DMK to serve the Tamil people.
She said that since the day she joined DMK, she was fulfilling the duties given to her by the party.
Khushboo said she decided to quit "since my commitment and service would continue to remain one way in the party" and the path taken by her was giving her mental tension.
Attempts to reach her were not successful and a person in her household said Khushboo has gone abroad.
Meanwhile, the DMK Monday announced an internal restructuring by increasing the number of district units, party general secretary K. Anbazhagan said.
In a statement issued here, Anbazhagan said the party decided to increase the number of district units to 65.
The party earlier this month appointed a group to recommend internal restructuring to make the organisational structure strong following its debacle in the general elections.
