The TDP chief also threw a challenge to YSR to hold direct polls to the post of mayor of Greater Hyderabad. 'There are 55 lakh (5,500,000) voters in the city, who are politically conscious. They will decide who is the best chief minister,' said Naidu.

YSR responded by saying he was ready for a referendum across the state on four points - credibility, corruption, governance and political murders.

There was utter pandemonium in the house amid 'war cries' between TDP and Congress legislators, who were seen gesticulating at and challenging one another.

However, the intervention by Praja Rajyam Party president Chiranjeevi and Lok Satta legislator Jayaprakash Narayan dampened the heat.

'The challenges and the counter challenges by the two leaders are distracting attention from the real issues of people. Let us use the same spirit to solve people's problems,' said actor-turned-politician Chiranjeevi while dismissing the idea of referendum.

Jayaprakash Narayan wanted to know from YSR and Naidu the article of the Constitution under which they propose to hold a referendum.

Meanwhile, Telangana Rashtra Samiti (TRS) leader Harish Rao demanded that the referendum be held on the demand for separate statehood to Telangana region.

Amid the uproar, Naidu wanted to say something but Speaker Kiran Kumar Reddy adjourned the house for the day.
