"We will support the demand (by the slain leader's wife KK Rema), we will not hesitate to ask for a investigation by the CBI into the conspiracy angle of the murder and write to the Centre again", he told reporters here.

He was responding to a question on Rema recently writing a letter to the Centre pressing for a CBI probe into the killing of her husband in 2012.

Chandrasekharan, a CPI-M rebel who floated a parallel Left outfit called Revolutionary Marxist Party in his home turf Onchiyam in north Kerala, was hacked to death in May 2012. A court in 2014 had sentenced 11 persons, three of them local CPI-M functionaries, to life imprisonment.

However, Rema had alleged that bigwigs of CPI-M were involved in the conspiracy to murder Chandrasekheran. Rema had recently approached the Union Personnel Ministry requesting to take a re-look into the CBI's stance that it cannot investigate the case.
