There are so many demands on your time, on your resources, and on the prestige of the government.

Like all of us, there were many facets to Margaret Thatcher's personality. In private she was kind, thoughtful, charming. Very attentive to her interlocutors. She took time to be concerned - she knew all about my children and wife Mila and so on.

When I appointed the Minister of the Environment to major cabinet status, the Planning and Priorities committee, the signals that that sent through Ottawa were major, because that's what the bureaucracy understands.

At summits Margaret Tatcher was the only woman. Always perfectly coiffed, splendidly dressed - beautiful maroon or dark blue suits. That lovely diamond brooch. She would never speak to an issue without having absolutely exhausted the research on the file. She spoke very confidently because of it.

Every argument that Margaret Thatcher ever made internationally didn't have a great deal to do with her contempt for Communism - she never really got into that. What she talked about was giving freedom to tens of millions of people in Central and Eastern Europe. She was an inspirational leader when it came to discussing her belief in freedom. More visceral and moral.
