Congress president Rahul Gandhi on Thursday demanded an investigation against Prime Minister Narendra Modi on his role in the Rafale deal, alleging that he was a "corrupt man" who helped Anil Ambani pocket Rs 30,000 crore in the purchase of 36 aircraft.

Gandhi's demand for a probe came a day after a report in a French publication that said Dassault Aviation, the manufacturer of Rafale, had to choose Ambani's firm Reliance Defence as its offsets partner in India as a trade-off for getting the deal. The Congress president did not provide any evidence to back his allegations. The government has been insisting it had no role in Dassault's choice of Reliance Defence.
