Normally reticent and a back-bencher, the Congress Vice President entered the Well for the first time in more than 10 years to join his party members in pressing for an adjournment motion to discuss the incidents of communal violence, a demand opposed by the government.
As the House assembled for the day, Congress pressed for suspension of the Question Hour to take up the debate immediately.
Parliamentary Affairs Minister M Venkaiah Naidu, while opposing the motion, said there was no communal tension in the country.
Amid the din, the Question Hour went on except for a brief adjournment.

Speaking to reporters outside the House, Rahul said Opposition was not being allowed to speak in Parliament and "it is completely one-sided, partiality", in comments seen as raising questions on the Speaker.
"We are not being allowed to speak in Parliament. We are asking for discussion. There is a mentality in the government that discussion is not acceptable. Everybody feels it, their party feels it, we feel it, everybody feels it," Gandhi said.
The Speaker rejected Rahul's allegation of bias and said equal opportunity is given to all members and parties. However, she maintained that if somebody chose to make allegations, she cannot help it.
Hitting out at Rahul, Finance Minister Arun Jaitley said his "contrived aggression" was a compulsion as the party leadership was facing a "palace coup" within, an apparent reference to demands from some Congressmen for Priyanka Gandhi to play an active role in the party.
