Marumalarchi Dravida Munnetra Kazhagam chief Vaiko leads protests in Tamil Nadu's Madurai ahead of PM Modi's visit. Releasing black balloons, the protesting party cadres raised slogans against PM Modi, alleging he betrayed the interests of Tamil Nadu on Cauvery and other issues. The MDMK cadres claimed that the Centre had accorded "permission to projects like neutrino and hydrocarbon extraction" which, according to them, would have an adverse impact on the livelihood of the farmers and also affect the common people.
