"Chatterjee had voiced his displeasure over the CPI-M voting against the United Progressive Alliance alongside the Bharatiya Janata Party." if he was true to the duties as speaker, he shouldnt have VOICED HIS DISPLEASURE OVER THE CPI(M) doing anything, isnt it....
truly an internal matter of CPI(M)... and he is not the first leader to be expelled from CPI(M)...
