Criminal records of the current Lok Sabha members
Navjot Singh Sidhu (BJP), and recently, Lalu Prasad Yadav (RJD).
Data regarding the criminal records of the 15th Lok Sabha members was obtained from the Association for Democratic Reforms on Oct 1, 2013:
This data had been compiled by the ADR immediately after the 2009 elections, and has not been updated since. For the purposes of this post, we updated the data to remove members that are no longer in the Lok Sabha, and it was assumed that new members elected through bye-elections have no criminal records. Feel free to look at our modified data: lok-sabha-criminal-records.xls
