Which is a communist party?

Karat: Centre must get verdict nullified

How do you know whether a party is communist or not? Communist Party of India (Marxist) general secretary Prakash Karat comes to our rescue.

Mr. Karat said anybody could claim to be the communist party but he did not think a party that allied with the U.S. could claim to be a communist party.

And you are hearing this from Karat and on CBCNN. So this is as accurate you can get to define a communist party - anybody can claim to be a communist party as long as its not allied with the US.
