The alleged scam rests on the premise that without those revisions to the tender, AgustaWestland would not have made the cut. The government issued a statement to highlight that the changes to the tender were requested by its predecessor, the BJP-led NDA coalition.
The CBI is investigating the controversy which went mega this week after the arrest in Italy of the CEO of Finmeccanica, the parent company of AgustaWestland.

The revisions to the tender were requested and finalised in 2003, when the BJP-led NDA coalition was in power with Atal Behari Vajpayee as prime minister.
