I think there are a number of reasons, not least of which is the personality of the Queen [ Elizabeth II]. It's very easy to underrate her significance. I think she finds the Commonwealth and her position as Head of the Commonwealth infinitely more interesting than being the Queen of England, because she has no significant role in the latter.

We will not allow to become a political issue in this country the question of Asianisation.

I wrote a letter to our Australian newspaper about three weeks before the invasion and I said, "Osama bin Laden must be on his knees morning and night praying to Allah that the Americans will invade." And, of course, he was, because nothing more advanced his cause - the cause of terrorism - than the invasion of Iraq. It was an absurdity.

I rang my friend Jim Wolfensohn, who was then running a private commercial bank in New York. I said, "Come up to Vancouver", and he did. I put my proposition to him. He said, "I think it could work." I said, "Will you help us?" He said, "Yes." So, I set aside senior people in our treasury and they worked with Wolfensohn and the investment sanctions were applied. And that's what brought the regime down. The last South African Finance Minister, Barend du Plessis, went on record as saying that it was the investment sanctions that put the final nail in the coffin of apartheid.

The essence of power is the knowledge that what you do is going to have an effect not just an immediate but perhaps a lifelong effect on the happiness and wellbeing of millions of people and so I think the essence of power is to be conscious of what it can mean for others.

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.
