The Bharatiya Janata Party on Tuesday trained its guns on Congress President Rahul Gandhi and his mother Sonia Gandhi over the tax fraud case pertaining to the National Herald matter. In a press conference, Union Minister Smriti Irani launched a scathing attack on the Congress leaders, alleging that Rahul Gandhi had hid assets from Income tax department. The Bharatiya Janata Party leader cited a note by former Reserve Bank of India Governor Raghuram Rajan, who has listed the over-enthusiasm of banks between 2006 and 2008 as one of the reasons behind the bad loans crisis. A Congress-led government was in power during the period.
