Presented by Jenni Murray. Including actor Ruth Jones on her portrayal of Hattie Jacques. We look at the ethics of paying for a surrogate mother and ask if the law on this issue needs to be updated. The rising number of widows and young women in Iraq finding themselves single because their generation of men has been decimated by war has led to a return of the practice of polygamy. We hear from MP Dr Nada Ibrahim and Hana Edwar from the Al-Amal (Hope) Charity to discuss this new issue for women in modern day Iraq. And we ask what is the special bond between mothers and sons? What happens when something - or someone - gets in the way?
