New Delhi, Jan 02 (ANI): Retired Lieutenant General PN Hoon on Thursday said that even though India has cancelled the AgustaWestland VVIP chopper deal, there should be a CBI inquiry to expose all the wrongdoings in the deal and the people involved. India cancelled the controversial Rs. 3,600-crore contract for 12 helicopters meant for VVIPs with UK-based AgustaWestland amid allegations that deal was riddled with kickbacks on Wednesday. The announcement came after a meeting between Defence Minister AK Antony and Prime Minister Manmohan Singh on Wednesday. The defence ministry has said that the "violation of a pre-contract integrity pact" led to the decision.
