Days before the Kerala Assembly Elections 2021, senior Congress leader PC Chacko, sent his resignation to the party's interim chief Sonia Gandhi. He alleged groupism amongst the top leaders in the state unit.

PC Chacko is a former Member of the Parliament from the Thrissur Lok Sabha seat. "I've been arguing with high command that this should be ended. But the high command is also agreeing to the proposal given by both groups," said Chacko at the press conference.

After announcing his decision to resign from the party he said, "I'd been deliberating upon this decision for past many days. I come from Kerala where there’s no Congress party as such. There are two parties – Congress (I) and Congress (A). It’s coordination committee of two parties functioning as KPCC.”

According to the announcement of the Election Commission of India, the assembly elections in Kerala will be held on April 6.
