Congress General SecretaryDigvijay Singh today wrote to Prime Minister Manmohan Singh demanding a probe into allegations of dubious funding of companies run by BJP president Nitin Gadkari.

In his communication, Digvijay Singh urged the Prime Minister to ask the Ministry of Corporate Affairs to institute an inquiry by the Serious Fraud Investigation Office (SFIO) into the matter, saying that, "a prima facie case does exist".

He was referring to reports related to the association of BJP chief with a Nagpur-based company Purti Power and Sugar Limited, regarding which 'irregularities' have come to the fore.

"Gadkari has also said that he is open to a free and fair investigation. Being the National President of BJP, it is in the fitness of things that his case is properly investigated and he gets a fair opportunity to prove his innocence and clear his name," Singh said.

It is for the first time that any Congress leader has demanded a probe into the issue.

The Party has so far been maintaining that there should not be any politics on the private business of individuals and unless some investigating agency stumbles upon any irregularity, there is no need for Congress to target the BJP chief.

Singh has also attached with the letter a report compiled from information taken from the official site of the Ministry of Corporate Affairs and said that findings of a TV investigation as well as this report make 'some very pertinent points that requires serious attention'.

In his letter, Singh, a known detractor of Gadkari, said that it is believed that the BJP chief had acquired Purti Sugar Mill, which had shut down.

Complimenting NDTV for the 'exhaustive investigation' carried out by it on PPSL, he said certain points require serious attention.

"The companies that bought equity in PPSL appear to be defunct companies which had not done business for a long time. Out of nowhere these companies got the capital to buy equity in PPSL, most likely from another layer of Shell Companies...

"Most of these companies have given bogus addresses... It is also interesting that all the companies have used a single email ID that is rajeshsharma54@yahoo.com," he said.

Singh mentioned in the letter that four names are common to list of Board of Directors of all the 18 companies. Gadkari had recently filed a defamation suit against the Congress general secretary.

At the AICC briefing, party spokesperson Sandeep Dikshit merely said that it was for the government to decide about probing the issue when asked whether the party endorses the demand made by Singh.

At the same time, he sought to insist that the allegations of corruption against Gadkari were 'qualitatively different' than those faced by Robert Vadra, son-in-law of Sonia Gandhi, when asked about parallel between the two episodes.

"The cases of Gadkari and Vadra are different. After the statement of the Haryana government and DLF, it is clear that no favour has been done to him. This issue is only political. Since somebody has made money, he should not be targetted only because he is related to somebody.

"We are also saying on Gadkari issue that let the government agencies first examine the issue and something comes out that the allegations are true, then we will see it," Dikshit said.

On BJP MP Ram Jethmalani asking Gadkari not to seek a second term in office in the wake of allegations of corruption against him, the Congress spokesman said it was BJP's internal issue.

"It is for the BJP to decide what kind of President they would like," he said.

A senior party leader, who declined to be identified, said that the continuance of Gadkari in such a situation is to the benefit of Congress.

Replying to questions why Congress is soft-pedalling the issue of Gadkari, Dikshit said, "There is no issue of compromise. Institutions will do their job. If they come out certain facts, political parties will respond... Every business deal of a private individual is not a political issue."

Asked about Digvijay's letter to the Prime Minister on the issue, Dikshit said that since a letter has been sent, 'let the Prime Minister take a decision on it'.
