Chacko is a former Member of Parliament from Thrissur Lok Sabha seat in Kerala.
Addressing a press conference, Chacko said he has sent his resignation letter to Congress president Sonia Gandhi.
Accusing his party of ignoring state leaders in the selection of candidates for the April 6 Kerala polls, Chacko said, “There is no democracy left in the Congress. The list of candidates has not been discussed with the state Congress committee.”
Miffed over ticket distribution in his home state, Chacko told the media that he had been considering the move for several days.
“I come from Kerala where there’s no Congress party as such. There are 2 parties – Congress (I) and Congress (A). It’s a coordination committee of 2 parties functioning as KPCC,” Chacko said at the briefing.
Chacko alleged that there are two dominant groups within the party – group “A” headed by Oommen Chandy and group “I” headed by Ramesh Chennithala.
Citing that Kerala is facing a crucial election, the veteran leader said, “People want Congress to come back but there’s groupism practised by top leaders of Congress.”
Earlier this month, Congress constituted screening committees for Kerala polls appointing H K Patil as the panel head.
The election for the 140-member Kerala assembly will be held on April 6.
