The case against Rajiv strongly rests on his "suspect actions", like not keeping Oza informed, canceling the visit of Bofors officials to India in July '87 on the plea of a constitution of a joint parliamentary committee and the haste showed in rushing through with the Bofors deal before March 31, '86. The CBI has banked heavily on Oza's statement, which it describes as "most damaging", showing the duplicity of Rajiv. According to Oza, who has recorded his memoirs in An Ambassador's Evidence, Rajiv Gandhi and members of the pmo indulged in a massive cover-up. The CBI has also relied on the statement of Arun Singh, former minister of state for defence, that he was personally in favour of scrapping the Bofors deal when the kickbacks story surfaced and was surprised why Rajiv persisted. The statement of Sarla Grewal, then personal secretary in the pmo, has also been recorded to support the CBI's thesis on the "swiftness shown" in the deal. But when the case does come for trial, all this may just be circumstantial evidence.
