Asserting that the government would do everything to ensure probity, transparency and accountability in the work of public authorities, he cautioned that creation of "mindless atmosphere of negativity and pessimism" over corruption could hurt the country's image and morale of the Executive.
Addressing 19th annual conference of CBI and state anti-corruption units here, Singh said, "newer modi operandi" are being adopted for corrupt activities as faster economic growth over the last two decades has "led to newer opportunities for corruption, ones associated with the specialisation and expansion of an economy".
He said amendments are being considered to the Prevention of Corruption Act, not only in view of the judicial rulings on its provisions, "but also with the purpose of filling certain gaps" in the legislation and bringing in line with international practices.
"Experience has shown that in the vast majority of cases, it is difficult to tackle consensual bribery and the supplier of the bribe goes scot-free by taking resort to provisions of the Act... Experience has also shown that big ticket corruption is mostly related to operations by commercial entities," he said, adding these would be taken care of in the proposed changes in the law.
"It is proposed to include corporate failure to prevent bribery as a new offence on the supply side," Singh said.
At the same time, he said the government is also examining how the Prevention of Corruption Act can be amended to protect honest public servants more effectively.
His comments came at a time when the government is under all-round attack over corruption with 2G spectrum, coal block allocation and Commonwealth Games scams being the notorious cases.
