The fact is that except Karat and Yechuri nobody else knows about this. I very much doubt if they would like to relinquish their bargaining position at this juncture. If they withdraw they stand no where. At the moment they are enjoying all perks without any responsibility. PM is stubborn because he wants his name written in the history with at least one action - right or wrong. There is nothing else in his credit for this period of 4 years.
