Launching an attack on the CPM over the political violence in Kerala, a BJP leader on Monday labelled the party as the "communist party of murderers".

BJP national spokesperson GVL Narsimha Rao said Kerala Chief Minister Pinarayi Vijayan is the "architect" of political violence and also accused him of shielding and patronising the CPM cadres involved in murders.

"CPM has actually been functioning as communist party of murderers. And there has not been any governance for that. Last 13 months our cadres, the BJP, RSS cadres have been killed in a very gruesome, barbaric and a violent manner. The people of this country know the real face of the communist party. Chief Minister Mr Pinarayi Vijayan was the architect of violence in the Kannur district, which is the epicentre of all such violence," ANI quoted Rao as saying.

"So rather than functioning as the CM of Kerala, he is functioning more like a chief murderer for the communist party in Kerala. This is highly condemnable," Rao added.

Echoing similar sentiments, another BJP leader Mukhtar Abbas Naqvi said Kerala has become a safe house for violence-loving elements under the LDF government.

"Kerala has become a safe house for such people. This has become so under the present government. Both the houses expressed concerns and discussed about this issue in Kerala. We also said to the Kerala government that whoever is the perpetrator action should be taken against them," Naqvi stressed.

A series of clashes between CPM and BJP activists had rocked Kerala last month in which RSS worker Rajesh (34) was murdered in Thiruvananthapuram.
