Union Minister of State for Commerce D. Purandeswari’s rivalry with sister Bhuvaneshwari’s husband, TDP chief, N. Chandrababu Naidu, for usurping her father N. T. Rama Rao’s legacy has got a shot in the arm. She’s looking the other way as actor brother- turnedpolitician N. Harikrishna goes on a ‘ Chaitanya Yatra’ against the division of Andhra Pradesh to expose the TDP chief’s ambivalence on the issue. Naidu has put on hold his own plans for a tour. Purandeswari’s gain? Harikrishna is pitching actor- son Junior NTR as the true inheritor to his paternal grandfather.
