BJP passed a strongly-worded resolution on corruption in which is patted its back for the arrest of former Telecom Minister A Raja and DMK MP Kanimozhi in the 2G spectrum allocation scam.
"It is evident that Manmohan Singh presides over the most corrupt government since independence. It lacks transparency, there is collusion at high level, no checks and balances and there is virtual collapse of system where scam after scam and scandal after scandal has become the order of the day," the party said in its resolution.
The document, moved by general secretary Ananth Kumar, also indicts Gandhi for not taking timely action.
"The Prime Minister maintained a 'conspiracy of silence', 'culpability of inaction', and 'guilty of gross indifference' when nation's wealth was being plundered by the then Minister right under his nose by a massive abuse of system and yet Manmohan Singh looked the other way. The silence of all powerful Sonia Gandhi was too conspicuous," BJP said.
The opposition party also mocked at the UPA-II pledge after it completed two years in office that it was serious about fighting corruption.
