"The CPI(M) will protest across the country against the BJP to expose its violence agenda in Kerala. We will fight the BJP with the support of people democratically," Mr Yechuri said.
He said the BJP had been trying to create communal polarisation in Kerala like in West Bengal.
"BJP President Amit Shah launched his march in Kerala early this week to play communal politics but people understand the BJP well."
Mr Yechuri also attacked Prime Minister Narender Modi-led central government for what he called was "failure on all fronts".
"The government has put the country in trouble with its anti-people policies like demonetisation and GST."
He said the PM Modi government neither generated jobs nor controlled price rise. "We will not allow the BJP to succeed in its communal agenda in Kerala," Mr Yechuri said.
