In 2007 May, Dinakaran, the newspaper run by Kalanidhi Maran, the elder brother of Dayanidhi Maran who was the central minister for IT and Communication, ran into a controversy when it published the results of a series of opinion polls which showed M. K. Stalin, the second son of Karunanidhi, having more approval (70%) than his elder brother M. K. Azhagiri (2%) as the political heir of Karunanidhi. It also showed others as 20%, possibly indicating Dayanidhi Maran and Kanimozhi. The Madurai office of Dinakaran was fire bombed by supporters of Alagiri and three employees were killed. The Sun TV office in Madurai was also attacked by the perpetrators.Phandis 2009, p. 145 A day after the incident, Prime Minister Manmohan Singh and Sonia Gandhi came to Chennai for felicitating Karunanidhi for 50 years in legislative assembly. Dayanidhi Maran, who usually accompanies Karunanidhi at every function, discarded the event as a mark of protest. On 13 May, the DMK administrative committee empowered Karunanidhi to remove Dayanidhi from the party. This subsequently led to his resignation from the central ministry. Following his resignation, the IT portfolio was allocated to Raja on 16 May 2007. On 17 October 2008, he submitted his post-dated resignation to the DMK party chief, M. Karunanidhi, in protest of the killings of Tamil civilians in Sri Lanka.
