Sonia Gandhi's son-in-law and businessman Robert Vadra questioned in connection with a 'benami' assets case. Speaking on this, he said that "there has been no tax evasion and every question was answered clearly." "23,000 documents were taken away from my office. They have more information about me than I have in my office today. Every question they asked was answered clearly. There is no tax evasion," said Vadra after ED raids and questioning by Income-Tax dept officials.
