In an exclusive interview to NDTV, Sushma Swaraj has said that if the BJP did plan a sting to prove that the Congress was willing to buy MPs to survive a trust vote in 2008, there's nothing wrong with that. However, she said that it is incorrect that BJP leaders are guilty of entrapment, and that the party is open to an investigation of its role in what's known as the "cash-for-votes" controversy. Ms Swaraj told NDTV's Barkha Dutt today that she stands by her demand for a CBI inquiry into the cash-for-votes allegation.
