MDMK Chief and DMDK-PWF convenor will contest from Kovilpatti constituency in the latest list of the DMDK-PWF candidates released on Saturday.
Kovilpatti has been a stronghold of the AIADMK for the past two years and the CPI before it. Vaiko previously contested from Virudhunagar under a BJP alliance during the 2014 Lok Sabha elections and lost.
He was arrested for a rail-roko campaign at Kovilpatti earlier this month.
Forty eight farmersâ€™ associations had sought support from the DMDK-PWF combine for holding rail roko across the State to highlight their demands. The Centre was keen on launching methane gas project and neutrino observatory in Tamil Nadu against the wishes of farmers, but the MDMK relentlessly protested against these projects, he said.
While police officials asked Vaiko and the agitators not to cause inconvenience to the public, the PWF leader lambasted the police saying that the agitation was being organised peacefully.
