Ashok Argal, one of the three BJP MPs who walked into the Lok Sabha waving bundles of notes in 2008, hours before Prime Minister Manmohan Singh faced a trust vote, says the police did not investigate properly what they were supposed to do. If they would have, then it would not have taken three years. He also maintains the three BJP MPs have spoken to Sonia Gandhi's political aide, Ahmed Patel, on the phone ahead of the trust vote in 2008.
