The most recent 'mother of the house', Harriet Harman has been an MP for 42 years. She has served in a number of cabinet positions, under six Labour leaders, both during government and opposition. She was also deputy leader of the Labour Party for eight years.

In some ways, her story is emblematic of how women's roles in society have changed: challenging familial stereotypes, dealing with sexual harassment, and as a trailblazing politician. On this episode, Katy Balls talks to Harriet about the influence of her family, why she got into politics, and why Labour hasn't had a female leader yet.
