BJP MP Kirit Somaiya today demanded that the government of the party-ruled Rajasthan register a criminal case against firms linked to Robert Vadra in connection with a land deal. Somiaya, who has been targeting Vadra, today wrote a letter to the Director General of Rajasthan Police, a day after the Enforcement Directorate issued a notice to a firm allegedly connected to the son-in-law of Congress chief Sonia Gandhi. "I would once again request the Rajasthan government's authorities concerned to register a criminal conspiracy case against Vadra group of companies. Vadra has dismissed the charges against him. The ED issued the notice in connection with its probe into alleged money laundering in a land deal in Rajasthan's Bikaner district.
