When many people struggle to maintain one relationship, why do some people enter into multiple simultaneous marriages? Lucy Ash speaks to polygamists around the world to find out why they were drawn to these complex arrangements and how they manage them.
Lucy hears about rotas, hierarchies and curfews from the stars of a popular South African reality TV show about a businessman, his four wives and their ten children. The creator of a dating website in Gaza explains why many of his clients are looking for second or third wives.
