YS Vijayamma wrote an open letter, putting her weight behind Congress leader YS Sharmila and said that it’s her “duty to speak up for the unfairly treated child”. This comes amid YSR Congress chief YS Jagan’s dispute with his sister Sharmila over an inheritance worth crores. Vijayamma wrote that Sharmila was not involved in the family business but worked selflessly in politics for Jagan.
