Swamy, who had earlier targeted MDMK chief Vaiko for flaying the government despite being in the alliance, accused PMK of being pro-LTTE and wrote on twitter that "PMK (founder S) Ramadoss should also depart from NDA..." Both Swamy and another BJP leader H Raja had been critical of Vaiko's comments against NDA on issues such as the Lankan Tamils issue and move to promote Sanskrit and Hindi and had asked him to leave the alliance.

Ramadoss has been critical of BJP-led government even backing Vaiko in the Swamy-Raja episode, and had on Monday opposed External Affairs Minister Sushma Swaraj's push for making the Bhagwad Gita as a national scripture.

Vaiko quit the alliance charging the Narendra Modi-led BJP government with betraying Tamil people by working with Sri Lankan government and pushing Hindutva agenda in Tamil Nadu. BJP, however, remained unfazed rejecting the party's contention that the Centre was acting against the interest of  Tamils and signaled that it would not like any of its partners oppose the government.
