The Opposition National Democratic Alliance and the Third Front on Friday continued to disrupt proceedings in Parliament demanding the constitution of a Joint Parliamentary Committee to go into the India-United States nuclear deal, leading to the adjournment of the Lok Sabha and the Rajya Sabha for an hour.

In Lok Sabha, Deputy Leader V K Malhotra demanded the suspension of Question Hour as soon as the House met for the day. His demand came in for sharp attack from the treasury benches with even some ministers joining issue.

This prompted BJP members to strom the well of the House even as Speaker Somnath Chatterjee pleaded with them in vain to allow Question Hour.

Chatterjee said a discussion on the Indo-US nuclear deal is scheduled on Monday, and at that time members could put forth their point of view.

The Opposition members were in no mood to listen and chanted slogans like 'We Want JPC' and 'Nahi Chalegi Tanashahi' (dictatorship will not be allowed), prompting treasery benches to counter with 'BJP Shame-Shame'.

As the din continued, Chatterjee adjourned the House till noon.

Rajya Sabha witnessed similar scenes as NDA and Third Front members were up on their feet as soon as the House met.

V Maitreyan (AIADMK) sought to know the government response to the demand for a JPC. He was supported by Sushma Swaraj, Arun Shourie (BJP) and Amar Singh (SP).

Chairman Hamid Ansari said, "Let the Question Hour proceed. There are other modalities of dealing with the issue," but his pleas for order went unheeded.

Soon, BJP members trooped into the well of the House shouting slogans for constitution of JPC, forcing the chairman to adjourn the House till noon.
