A cold war, that has been brewing between TDP supremo Chandrababu Naidu, Nandamuri Harikrishna and his actor son junior NTR has come to the fore with Jagan Mohan Reddy's YSR Congress party executing its 'Operation K'.

Recently, YSRCP chief Jagan Mohan Reddy hugged TDP Vijayawada Urban unit president and jr. NTR's close follower Vallabhaneni Vamsi Mohan, a Kamma, in full public glare. This Vamsi-Jagan meeting led the TDP leadership to believe that Vamsi is getting closer to YSRCP. Immediately TDP supremo issued a show-cause notice to Vamsi. Though Vamsi has denied the reports that he is joining YSRC, the TDP is not in a mood to believe him for the fact that Vamsi is a close follwer of Nandamuri Harikrishna. Vamsi, MLA Kodali Nani and Harikrishna's actor son jr. NTR are close chums and jr. NTR is believed to be behind Vamsi meeting the YSRCP chief.

TDP founder lete NT Ramarao's son and actor Nandamuri Balakrishna is believed to have asked his brother-in-law and TDP chief Chandrababu Naidu to act tough against Vijayawada TDP leader Vallabhaneni Vamsi for his bonhomie with their rival Jaganmohan Reddy. According to highly-placed sources, Balaiah's anger forced Naidu to react with an unusual speed in serving a show-cause notice to Vamsi on Saturday. On the otherhand, Junior NTR was furious at Naidu as TDP followers were called for the Krishna district bandh the day his new film 'Dammu' was released. Ignoring the pleas of local leaders Kodali Nani and Vamsi, who are close to the actor, Krishna district TDP chief Devineni Umamaheswara Rao went ahead with the bandh on Friday. While the noon shows were cancelled in Vijayawada due to the bandh, Kodali Nani forced the owners of theatres in Gudivada to screen the film despite the bandh. Sources said that Junior NTR and Vamsi discussed the issue at length and the former reportedly encouraged Vamsi to go and meet Jagan in full public view to irritate Naidu.
