I went along with it, and wanted to appoint a significant figure in Malcolm Fraser. I didn't have high hopes that they'd be able to do anything, but something was worth a try.

Do you know why I have credibility? Because I don't exude morality.

One other thing: at the meeting in Canada, [there was] the coup in Fiji. This comes to an important part of the Commonwealth: the role of the Queen [Elizabeth II]. I had absolutely just enormous respect for her as leader of the Commonwealth. You could talk to her about any of the fifty-one countries of the Commonwealth and you could have an intelligent conversation with her about the economics, the politics. She really immersed herself in the Commonwealth.

I was used on a number of occasions by the United States and China as a conduit. For instance, I was up there talking with the Chinese leadership and they said to me that they were a bit concerned that the Americans had a misunderstanding about their relationship with the Soviets. There was some suggestion that there was a rapprochement developing between China and the Soviets, but nothing could have been further from the truth.

When George Bush Senior [George HW Bush] was getting his alliance together to go into Iraq - to kick the Iraqis out of Kuwait - he rang me up. I was very close to George Bush Senior; I got to know him well as Vice President to Ronald Reagan. And George rang me up and said, "Oh, Bob," he said, "I'm having trouble with Brian [Mulroney]." He said, "He's got a big wheat trade with Iraq, and he doesn't want to upset that." I said, "You leave it with me."

I had no time for Indira Gandhi. She was too much in the Russian camp for my liking.

I respected [Margaret Thatcher] enormously. She had great integrity in that respect.
