Don't talk to me about what's happened since [Nelson] Mandela! His successor was absolutely hopeless - "no such thing as AIDS" - and this present President... It's a tragedy, you know, what's happened there post-Mandela, because he was an iconic figure.

I had a very close relationship with [Brian] Mulroney.

If you've got good chemistry at the top, it's an enormous help. It's easy to have good chemistry with some, not so easy with others. With [Robert Mugabe], for example.

I assumed the leadership within the Commonwealth for the fight against apartheid. I was very much assisted by Brian Mulroney, the Prime Minister of Canada, [and] Rajiv Gandhi, when he became the Prime Minister of India. And there were trade sanctions.

One of the features of the Commonwealth Heads of Government Meetings was [that] she [ Elizabeth II] would have a meeting with each of them. You'd have an allotted time.

I rang Brian [Mulroney] up. I said, "What's this bloody nonsense. You've got a wheat trade with Iraq and you won't come aboard?" I said, "We've got a bloody big wheat trade too, so get your priorities right." And he said, "Okay, Bob. I'll come." I rang George and he was very appreciative.

The personality of the Queen [ Elizabeth II]... For instance, once she goes - if she's ever going to die, it seems to be questionable - if Charles [of Wales] were there, whether there'd be the same sort of cement is very questionable, I think.
