The Book Club: with former Australian PM Julia Gillard

Sam's 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. Sam asks 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.
