DMK activists will "fill the jails" across Tamil Nadu July 4 to denounce the "vendetta politics" of the AIADMK government, party president M. Karunanidhi said Friday.
And if they are not released in time, DMK MPs and legislators will still vote in the presidential election next month, he told reporters.
He said he had called for the protests as the government had invoked the Goondas Act on one of its leaders and former minister Veerapandi S. Arumugam.
Earlier, the party's executive committee decided to "fill the jails" July 4 to condemn the continuing arrests of former DMK ministers and other party members.
Chief minister J. Jayalalithaa has said that the arrests were being made following complaints by ordinary people.
