Once a person becomes a Lok Sabha speaker he does not belongs to any party. He belongs to the house. He should belong to the house. His parent party can request him but can not dictate him to abandon his post. CPM can even deny him to field him as one of their candidade. But no this action of expulsion is nothing but farcical. We need more strong willed and couragious person like Mr. Somnath Chatterji.
