Singh was expelled for six years from the Bharatiya Janata Party (BJP) at the end of March this year after he decided to contest Lok Sabha Parliamentary Elections as an independent candidate from Barmer in Rajasthan against BJP's official candidate Sonaram Choudhary. Choudhary won the election by a margin of over 87,000 votes.
