The same question put by Chakravarthy,the minister o Wast Bengal is going to be raised by the entire nation very rightly.The left parties have no answer than to gulp their own saliva.
As for Somnath's continuance as speaker or not is concerned,constitutionally speaking- "Yes", he could since the office of speakership is above politics and it is the entire house that elected him.But morally speaking-"No" since his entry into parliament is owing to his having been elected on party ticket and NOT as an independent.
