The proceedings in Parliament continued to be disrupted for the fourth week over the opposition demand for a JPC probe into the 2G spectrum scam. Both the Lok Sabha and the Rajya Sabha had to be adjourned till noon following pandemonium with opposition members trooping into the wells. As soon as the two houses assembled for the day, the members were up on their feet raising pitch. The opposition demanded JPC while the ruling members demanding sacking of the Karnataka Chief Minister, B S Yeddyurappa. Earlier, the Lok Sabha Speaker, Mrs Meira Kumar congratulated the Indian Contingents for their commendable performance in the recently concluded Asian Games in China.
