Caretaker Irrigation Minister T. Harish Rao said there was no ideological base for Congress and its alliance partners to forge a tie-up except the hunger for power. Addressing a meeting at TRS office here on Friday on the occasion of BJP president of Sangareddy district, K. Buchi Reddy, joining the former party, Mr. Rao highlighted the contradictions within the grand alliance comprising Congress, Telugu Desam, Telangana Jana Samiti and CPI. The Telugu Desam was formed on the plank of protecting the self-respect of Telugu-speaking people, but its president N. Chandrababu Naidu mortgaged their interests with Congress leadership in New Delhi. On the other hand, TJS president M. Kodandaram sacrificed the self-respect of Telugu people. Mr. Kodandarm joining hands with Mr. Naidu was an insult to the people of Telangana as the latter set up obstacles to the State development at every stage. Mr. Rao wondered whether the parties in alliance would work for the development of Telangana going by the manner they hankered for power in New Delhi. Mr. Kodandaram bargained for a mere two seats for TJS though Congress was unwilling to concede any for the party. The caretaker Minister also said there was no truth in the claim of Mr. Naidu that he would not interfere in the affairs of Telangana. The truth, however, was that he complained to the Centre against construction of Kaleswaram and Palamuru-Ranga Reddy lift-irrigation projects.
