The PPP route for infrastructure building also causes a spurt in corruption, he said.

Multi-crore infrastructure projects being built through the public-private partnership (PPP) model could lead to rising corruption, CBI director Ranjit Sinha has said. The PPP route is "full of pitfalls", he reportedly said, referring to collusion between government officials and companies seeking and bagging these contracts, according to a report in The Economic Times.

“This route is full of pitfalls and it has opportunities for corrupt activities with big scope for collusion among promoters of consortiums to whom such projects are awarded and corrupt public servants at the decision-making level,” Sinha said, according to the report.

The comments were made on November 6, at a training academy in Madhya Pradesh.

Apart from expressing concerns about the PPP route, the CBi director also said the Congress party's Right to Food law could turn into an avenue for corruption.

“The proosed Right to Food Bill is going to cost the public exchequer an astounding 1 lakh crore every year. It is going to be a formidable challenge to ensure that these huge outlays are converted into outcomes and are not just siphoned off ...” he said.
