I am not a supporter of CPI-M or Prakash Karat. But what Somnath Chatterji did was wrong. Issues can be debated within party forums, but when it comes to decisions on voting in the parliament, it should be a collective decision.
At other times, due to difference of opionion an MP should resign from the Party and Parliament and contest elections again.
If our leaders behave this way, would it be acceptable, if an jawan gaurding indo-pak betrays india stating 'Acting according to inner conscience' would it be acceptable.
