Union Finance Minister Arun Jaitley on Friday attacked the Congress, party president Rahul Gandhi and UPA chairperson Sonia Gandhi for their alleged involvement in the controversial Augusta-Westland VVIP chopper scam. Addressing a press conference in New Delhi, Jaitley said the Enforcement Directorate (ED) probe has blown the lid of corruption of the Congress Party though it is trying hard to cover up its past mistakes. Jaitley said abbreviations like RG, AP, FAM were used to hide the identity of the people involved in the Rs 3,600 crore AgustaWestland scam.
