NEW DELHI, INDIA :  Stunning details of millions of dollars of payments by several foreign defence companies to alleged Indian arms dealers have emerged in secret documents accessed by the BBC and The Guardian, and shared with The Hindu.

Among the key details are remittance of almost €100 million (approx Rs. 730 crore) in just 12 months by Russian arms firms into accounts of companies controlled by alleged arms dealer Sudhir Choudhrie and his family and close associates; and about £10 million paid by British company Rolls-Royce to firms linked to Mr. Choudhrie.

Mr. Choudhrie’s lawyers told the BBC that the former Delhi resident, who now lives in London, has “never paid bribes to government officials or acted as an illegal middleman in defence deals.”

The Hindu newspaper claimed it got access to confidential details, including a key banking document of October 2, 2008 showing the massive payments into various accounts controlled by companies run by the Choudhrie family.

BBC’s Panorama, the current affairs investigative programme, has claimed that Rolls-Royce made secret payments of around £10 million to an unregistered Indian agent. Rolls-Royce says it has zero tolerance of bribery and corruption. “Panorama has learned Rolls-Royce paid the money to companies linked to arms dealer Sudhir Choudhrie,” the report says.

In 2014 Mr. Sudhir Choudhrie and his son Bhanu were arrested as part of U.K.’s Serious Fraud Investigation Office inquiry into Rolls-Royce. Both were released without charge.

In what could raise serious questions about India’s massive defence deals with Russia, documents show that Russian arms companies made massive payments to Mr. Choudhrie and family.

BBC said leaked documents from the Choudhries’ Swiss bank account show that the family’s companies were paid almost €100 million by Russian arms firms in one 12-month period alone.
