A week after activists-turned-politicians Arvind Kejriwal and Prashant Bhushan made allegations of corruption against Congress President Sonia Gandhi's son-in-law and businessman Robert Vadra, now Kejriwal led-India Against Corruption has said it will expose a top political leader in the coming week. The speculations are rife that IAC will be exposing a top Maharashtra based leader. IAC, in its first expose, alleged that Vadra was hugely favoured by realty major DLF between 2007 and 2010. In reply to IAC's accusation, Vadra dismissed their allegation referring them as 'utterly false, entirely baseless and defamatory'.
