My guest in this week's books podcast is the former Australian Prime Minister Julia Gillard. Along with the economist and former Nigerian finance minister Ngozi Okonjo-Iweala, Julia has written a new book called Women and Leadership: Real Lives, Real Lessons, which includes interviews with women who've reached the top roles in global institutions, from Christine Lagarde and Joyce Banda to Michelle Bachelet and Theresa May. I asked her about her own time in politics, what she'd have done differently, whether Australia is more sexist than the UK, and her notorious 'misogyny' speech - plus, what she thinks her old sparring partner Tony Abbott has to offer the UK as a trade adviser.
