It is a known fact that in CPM there are two groups called Kerala group and Bengal group.Karat is a Malayali and wants to get supremacy over WB party.Kerala lobby always opposed Bengal leaders like jyoti Basu.They even banned Basu's biography in Malayalam for his "historical blunder" theory.Unlike Congress leaders of Kerala who are all highly educated ones, the Kerala CPM leaders are school drop-outs and iliterates like V.S Achuthanandan (formerly a tailor) and Pinarayi Vijayan( formerly a toddy-country liquor- worker).But WB leaders are educated ones like Basu and Somnath. The fight within the party between Bengal and Kerala is reflecting in this Somnath episode.
