Cpi[m} did a right think in expelling the speaker from the party for indiscipline.He should have resigned the moment the party withdrew support to the upa. How can he enforce discipline in parliament when he himself violated party rules.Further he is highly partistan.He is out &out supporter of upa& hence people from upa prostrate before him including the priminister. He was not born as speaker. He acqired it by election. In view of the above he should resign immediately.
