"We were great mates [with Rajiv Gandhi]: very, very, very close friends. In fact, on my visit to India as Prime Minister, we were going to his home for dinner. There were two aspects I remember: one is him saying how he had trouble with his security people, because they insisted he wears a vest. He said it was very uncomfortable and he often took it off, but of course, in the end, it wouldn't have mattered if he'd been wearing three vests - he would have been gone."
