Which slain person are the Hinduja brothers pointing fingers at for being an agent in the Bofors deals?

During the legal proceedings of the Bofors scandal, the Hinduja brothers suggested that the Swedish Prime Minister Olof Palme, who was assassinated in 1986, might have been involved in the deal's commissions. This was part of their defense strategy to distance themselves from the allegations of receiving illegal kickbacks. The Bofors case was a major political scandal in India involving the purchase of howitzers.
