Chennai, Memes mocking DMK President M.K. Stalin aired on Sun News channel have angered the party leaders.
The memes said to be aired by oversight on Monday are said to have cost some people their jobs at the channel, said an insider.
The Sun TV network is promoted by Kalanidhi Maran, a relative of Stalin.
The party's Lok Sabha member representing Dharmapuri constituency, S. Senthilkumar, in a tweet condemned the airing of the memes, if they were really shown.
"If not real, issue a clarification," he said.
"Strongly condemn this insensitive act," Senthilkumar tweeted.
He also said the channel should not anger the party cadres. "Let things like this never happen," Senthilkumar said.
Senthilkumar was not available to comment when contacted by IANS.
