BJP today hit back at Congress President Sonia Gandhi defending son-in-law Robert Vadra saying it has exposed the farce of Congress that he is merely a private citizen. The party also took a dig at Mrs Gandhi over Shahenshah jibe against Prime Minister Narendra Modi, saying those who behaved and ruled like this were sent packing by voters in 2014 Lok Sabha elections. <br/><br/>Party Secretary Shrikant Sharma mocked the Congress Chief's challenge to the government to order a probe into the accusations against Vadra and said the opposition party has dubbed such enquiries as vendetta earlier.<br/><br/>Media reports say Vadra had bought a benami house in London in 2009 by an arms dealer who was raided last month for financial crimes. Reacting to it , Sonia Gandhi had dared the Centre to order an impartial probe and also attacked the government over the celebrations of two years in office, describing Mr. Modi as Shahenshah.
