CPM is wrong in dragging speaker into controversy at this stage. He has to remain there to see through the trust vote session when parliament meets. when voting takes as per conventions which britishers follow (we hav been takin cues from britishers in many instances) is - in the first instance, he votes with the treasur bench, that is UPA. and still it ends in a tie, needs another voting, he can then vote with the opposition. will he do that. only time will tell that. lets wait till then.
