on 15 April 2011, he filed a 206-page petition with PM Singh seeking permission to prosecute Sonia Gandhi on charges of corruption. He also raised doubts regarding her acquisition of Indian citizenship. Swamy filed documents in the court to prosecute Minister of Home Affairs P. Chidambaram by including a 15 January 2008 letter written by Chidambaram to Prime Minister Manmohan Singh. Swamy also placed on record the certified copy of the minutes of a meeting between Chidambaram, Raja and the prime minister during the tenure of Raja as the MOC&IT. Since criminal charges were filed against the accused, but no evidence was given by Swamy or the CBI, all the respondents have got bail as of July 2012.
