Subramanian and Rajendran, who are in their late fifties, died of heart attack in Mayiladuthirai and Nagapattinam districts of the state.
Mr Karunanidhi was admitted to Kauvery Hospital on July 28 after suffering a drop in his blood pressure and a urinary tract infection. Chants of "Ezhundhu Vaa Thalaivaa" (Awake, our leader) and "Vaa, Vaa, Gopalapuram Polaam Vaa" (Come, Come, let's go to Gopalapuram) could be heard outside the hospital.
"We had met CM and submitted a request for a "Samadhi" near Anna memorial, he had accepted our request then, but has not communicated anything in this regard till now: Durai Murugan, DMK principal secretary, said".
As a high school student, Karunanidhi founded the Tamil Nadu Tamil Manavar Mandram, the first student wing of the Dravidian Movement, which campaigned against the notion that Brahmins, the highest caste in Hinduism, in Tamil Nadu and Hindi speakers from northern India were considered superior.

Karunanidhi was chief minister of Tamil Nadu five times and successfully contested 12 state elections, building legions of supporters on the way.
Karunanidhi made his presence felt in Tamil cinema as a playwright and screenwriter.
"He is, without a doubt, the most senior statesman in the state's political arena". After Jayalalitha's death and Karunanidhi's demise, there will be a vacuum left in Tamil Nadu politics.
July 27, 1969: Elected as President of DMK, a post he held till the end. The same year he parted with 50% of the seats to the Congress in the Assembly elections but the alliance came a cropper and MGR won. As the popularity of the DMK continued to fall, two years later, in 1991, the DMK was easily defeated and Jayalalitha became the Chief Minister. But Tamil Nadu and Tamils will first remember him as one indefatigable politician who never gave up. "DMK working president MK Stalin asks the party cadres to maintain peace and adhere to party discipline", the party said in a statement.
