According to media sources, jagan is furious that sharmila gave her statement to the CBI. He allegedly told his mother about his anger in a phone call. He claimed that despite his best efforts to exercise discipline, sharmila was hurting both the reputation of his party and himself by engaging in such behaviour. If these rumours are true, jagan and Sharmila's distance has grown too great to be closed. Given that she has nothing to gain politically or otherwise, one may ask why she has adopted such a confrontational stance toward her brother.
If sharmila is attempting to extort jagan in exchange for political favours or real estate, her efforts will fail and undermine the ysr family's reputation as a whole. She hasn't yet commented directly on jagan, but if she does, the connection is severed forever!
