In May 2006, Dinakaran published the results of a series of opinion polls which showed politician M. K. Stalin having a greater approval rate than his elder brother M. K. Azhagiri to succeed Karunanidhi as the chief of Dravida Munnetra Kazhagam. As a result, the Dinakaran office at Madurai was fire bombed killing three employees.[6] This led to the resignation of Central Minister Dayanidhi Maran, brother of Kalanidhi Maran from the Union Cabinet.[7]
