When I was growing up, I was lucky to benefit from a first class education.

My pledge to you is that the SNP will put women and gender equality right at the heart of the Westminster agenda.

True gender equality in Scotland - and elsewhere - is still some way off.

I'm manifestly not the same as Alex Salmond. I'm a different gender, for example... I'm being flippant, but maybe this is a partly gender-driven difference: I'm very keen that we find a way of reaching out across party divides to find things we agree on, as well as the things we disagree on.

I do have friends that are Republicans, and we have very spirited conversations on a whole range of issues. I am often baffled by why they are Republicans, but I enjoy the dialogue and can move beyond politics to find common ground in my personal relationships.

That's what representative democracy is about, is members going to Washington but coming home and answering the tough questions.

There was a widespread indignation in the American media. They were saying, 'How can you make a movie during an election that's about politics? What are you doing? Are you trying to influence people's lives?' To which my response was, 'Well, I hope so.'

There's a lot of work being done through the innovation arm of the World Bank, at the World Bank Institute. There's a lot of work that we at the Rockefeller Foundation are doing and funding towards that end, and increasingly, the U.S. government is getting engaged.
