CBI is stellar in probing Opposition leaders, but what happens to corruption cases against BJP's BS Yediyurappa, Mukul Roy, Himanta Biswa Sarma

Central agencies have been remarkably on the ball in pursuing all kinds of cases against political leaders, or people connected to them, who are in opposition to the ruling BJP. CBI, ED, and I-T dept have played stellar roles in pursuing inquiries and detaining people against whom prima facie cases have been made out. The arrest of P Chidambaram on Wednesday night is a classic case in point.
