"He does not know whether he is reading his speech or someone else's speech", Yadav said without naming Krishna who was occupying the front bench during the debate on Motion of thanks to the President for her Address.

Krishna had mistakenly started reading the speech of his Portuguese counterpart at the UN Security Council. The Minister, however, rectified the mistake after it was pointed out by an official.

Yadav's remark that Krishna was sitting like a "great man...see his posture" evoked sharp reaction from ruling members, who accused Yadav of making disparaging personal remarks.

Referring to 2G spectrum allocation scam, Yadav said that Telecom Minister Kapil Sibal, an eminent advocate, was treating the nation like a "legal chamber." Sibal had earlier described the report of the Comptroller and Auditor General (CAG) on 2G spectrum allocation as "utterly erroneous." The ruling party members also objected to his remarks against Sibal.
