Advani demands investigation in 'cash issue'

"On the basis of whatever happened (on the floor of the House), we can demand from the Speaker, that as the issue is so serious, that a detailed investigation should be done," Advani told reporters here.     

Advani's demand came shortly after unprecedented scenes were witnessed in the Lok Sabha when a BJP MP waved in the well of the House wads of currency notes offered as a bribe.
