Just as Urban Development Minister M Venkaiah Naidu began addressing a press conference in Rajkot last week, some Congress workers rushed into the conference hall and disrupted the proceedings. A heated discussion ensued between Congress and Bharatiya Janata Party workers. The situation was brought under control only after the police intervened. A thoroughly miffed Naidu later said the "cheap tactics" of members of the Congress would turn it into a "cheap party". "They are not doing this just here; they are doing it at the national capital -not allowing both the Houses (of Parliament - the Lok Sabha and the Rajya Sabha) to function smoothly," he said.
