i didnot like the rough ways of CPM. But still i like to congradulate them for their bold decision. Expelling a senior leader like Somnath is not a easy decision.But a cadre party like CPM just shown that nobody is above party rules. For a communist, compromising on ideology for "money & Power" is the worst thing to do. Somnath chattergee become power greedy & deserved to be treated as non-communist.
This strong democratic party structure & rules are the reason,why CPM is still the strongest & growing communist party in India.
