Soon after Speaker Meira Kumar made an obituary reference in the Lok Sabha on the demise of former member Prabhat Singh Chauhan, who passed away on July 1, members from the National Democratic Alliance and some Left parties trooped into the Well.
Most of the Bharatiya Janata Party members, who refused to heed to Kumar's appeal for peace, were heard demanding Dr Singh's resignation in the wake CAG reports on coal block allocation and two other issues.
Amid din, Minister of State in the Prime Minister's Office V Narayanasamy also appealed to the opposition members to allow the House to run.
As the opposition members were unrelenting, Kumar adjourned the proceedings 2 pm.
In the Rajya Sabha, which witnessed two adjournments before noon, BJP-led NDA members were on their feet shouting slogans demanding the PM's resignation. "Istifa do, istifa do, Pradhan Mantri istifa do (Prime Minister resign)," they chanted.
Chairman Hamid Ansari told members not to raise slogans and asked senior BJP member M Venkiah Naidu as to what he wanted to speak. Naidu then said, "We want the prime minister to go" and not a mere statement on the issue.
Amid slogan shouting, Minister of State for Parliamentary Affairs Rajiv Shukla said the opposition "should not run away from discussion".
"Koyle ki dalali hai, sari Congress kali hai" (there is scam in coal allocation, Congress is responsible), some opposition members shouted.
Ansari then adjourned the House for 30 minutes.
When the Rajya Sabha reassembled, similar scenes were seen and the House was adjourned till 2 pm.
