The Lok Sabha was adjourned twice Monday as opposition members disrupted the proceedings over the allocation of 2G telecom spectrum, the demand for a caste-based census and the introduction of the foreign university bill.

When the house assembled for question hour, members of the AIADMK, Rashtriya Janata Dal (RJD) and Samajwadi Party (SP) walked towards the speaker's podium, raising slogans and brandishing copies of a national newspaper that carried reports of alleged financial irregularities on the part of Communications and IT Minister A. Raja over the 2G spectrum allocation.
