In his last campaign rally for the February 16 Mumbai Corporation elections, Shiv Sena leader Bal Thackeray targeted Sonia Gandhi's son-in-law, Robert Vadra, for his alleged involvement in the 2G spectrum scam. “Look at the way dynastic rule is manifesting itself in the Gandhi family. Sonia's son, daughter, daughter's husband, their children are all donning the mantle of dynastic rule. Mr. Vadra has opened a new can of worms in the Congress. He himself is involved in 2G scam, but he is now given entry in politics,” Mr. Thackeray said at the rally of the Shiv Sena-BJP-Republican Party of India combine here on Monday.
