Businessman Robert Vadra cannot be arrested till February 16 in an alleged money laundering case, a court in Delhi said today. His lawyer said Mr Vadra will join investigation in the case filed by the Enforcement Directorate over alleged wrongdoing in a deal of a London-based property worth 1.9 million pounds. The husband of Congress leader Priyanka Gandhi Vadra, who was recently appointed in-charge of eastern Uttar Pradesh where the Lok Sabha constituency of Prime Minister Narendra Modi is also located, denied the probe agency's allegations as "political vendetta in an election year".
