The CPI-M on Saturday asked the party-led Kerala government to register a case against Madhya Pradesh RSS leader Kundan Chandrawat, who declared a Rs 1 crore bounty for beheading Chief Minister Pinarayi Vijayan.

Addressing reporters here after a meeting, Communist Party of India-Marxist (CPI-M) state Secretary Kodiyeri Balakrishnan said the Vijayan government has no option but to register a case as he did not expect any action from the Bharatiya Janata Party government in Madhya Pradesh, where the speech was made.

"Even the NIA (National Investigation Agency) can go forward and register a case, but that also won't happen because the country is ruled by the BJP and hence no case would be registered," Balakrishnan said.

"So, we (the CPI-M) have asked the Kerala government to register a case against the RSS leader given the graveness of his comment, as it could have an impact in our state," said Balakrishnan, a former Home Minister.

He said that the RSS taking action against Chandrawat was not enough and in the larger interest, a case should be registered.

Following a huge public outcry, the RSS leader was stripped of his posts on Friday.

On March 1, Chandrawat declared the bounty in the presence of BJP MP Chintaman Malviya, BJP MLA Mohan Yadav and other Rashtriya Swayamsevak Sangh leaders. The Ujjain video went viral.

On Thursday, Chandrawat said he did not regret his remarks even as the Kerala unit of the RSS claimed Chandrawat did not speak for the organisation.

Chandrawat, RSS Ujjain's Sah Prachar Pramukh (Regional Deputy Publicity Head), had on Wednesday announced a reward of Rs 1 crore to anyone who brought the severed head of the Kerala Chief Minister.
