Accusing the government of misusing the Central Bureau of Investigation (CBI) as a political tool, Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA) MPs Thursday staged a sit-in in Parliament House premises.

Senior leaders of the NDA, including L.K. Advani, Leader of Opposition in the Lok Sabha Sushma Swaraj and her counterpart in the Rajya Sabha Arun Jaitley and other MPs of the BJP and other NDA constituents attended the protest in front of Mahatma Gandhi's statue on the Parliament House premises.
