The CPI (M) has accused BJP President Amit Shah of unleashing "lumpen politics" against it in Kerala but said the Marxists won't be cowed down.
"Amit Shah has embarked on a dangerous course of inciting violence against the CPI (M) by levelling false charges and accusations against the party," CPI (M) journal "People's Democracy" said in an editorial.
Shah launched a Bharatiya Janata Party 'yatra' in Kerala on Tuesday, starting from Kannur district where he blamed Chief Minister Pinarayi Vijayan for the political killings in the state.
"Filled with the arrogance of power, Amit Shah thinks that he can bulldoze the Sangh politics into Kerala using the false flag of red terror," the editorial said.
"This, in itself, shows the inability of the BJP-RSS combine to counter the CPI (M) and the Left politically in Kerala."
The Communist Party of India-Marxist added: "Amit Shah is the last person who should be accusing an elected Chief Minister of being responsible for murders."
It pointed out that as the Home Minister under now Prime Minister Narendra Modi in Gujarat, Shah was booked in a false encounter case in which Sohrabuddin and his wife Kauser Bi were killed by police while in their illegal custody.
"He was discharged in the case by the Mumbai High Court but his sordid record as a minister, during which period many false encounters took place, has qualified him as a specialist in 'encounter politics'."
Shah has called for protests by BJP workers outside the CPI (M) headquarters in New Delhi every day till October 16.
"The fact that the ruling party of the country is daily organising protests outside the office of a national political party speaks much about the lumpen politics that Amit Shah has introduced.
"There is no way such intimidatory tactics will work as far as the CPI (M) is concerned," it added.
