In 1972 the United Nations decreed that there should be an International Women’s Year, and 1975 was designated as the first one. For many women, it must have seemed to mark a significant advance. For many men, I expect, it came with a slightly guilty feeling; it probably seemed a bit quaint or unnecessary. Well, it was still a man’s world then, even though we British had a queen and in 1975 the Tory Party had, to its considerable surprise, found itself with a woman leader. This was all the more remarkable if you remember that Margaret Thatcher was elected Leader by only her fellow Tory MPs, almost all of them men.
