I think the problem is, exceptional women will always succeed. But there are plenty of less-exceptional men who succeed. Until we get the less-exceptional women succeeding equally, we do not have full equality.

I feel very strongly about contraception even though I know people say that, as a good Catholic girl, I shouldn't. But I disagree because I think one of the keys to women's progression in the 20th century is being able to control their fertility.

My own foundation concentrates on women's economic empowerment on the basis that if women have their own money and are able to support themselves, they can make choices about what happens to them in their lives, about whether they have education, whether they get married, and what happens to their children.

Many of the big decisions over progression, promotion and future career trajectory are taken when people are in their late twenties and thirties, putting women at a huge disadvantage because this is the very time they are most likely to be having a break to have children.
