AIADMK Coordinator and Deputy Chief Minister O.Panneerselvam said that under the AIADMK-led alliance for the 2019 Lok Sabha polls, "the PMK will support AIADMK in the assembly by-elections to be held in 21 constituencies."
“This is a mega and strong alliance that will win in the Lok Sabha polls,” PMK Founder S Ramadoss told reporters.
He said the party has submitted several conditions which AIADMK has agreed to fulfill.
PMK's requests for AIADMK include declaration of Cauvery delta region as a protected region, a caste-based census; release of the seven persons convicted in former Prime Minister Rajiv Gandhi assassination case; implementation of old pension scheme for government employees, preventing Karnataka from building a dam across Cauvery at Mekadatu; waiver of farm loans and getting Tamil Nadu exempted from the common medical entrance exam or NEET exam.
The development comes ahead of a likely announcement of a BJP-AIADMK alliance today. BJP President Amit Shah and Railways & Coal Minister Piyush Goyal are in the city today.
