In this episode of the Dead Sibling Society, Gracie and Callum are joined by Sarah Brown, chair of global children's charity Theirworld and wife of former British Prime Minister Gordon Brown. Gordon and Sarah lost their daughter Jennifer when she was just ten days old in 2002.

In a revealing, emotional interview, Sarah tells the pod about her links to Callum and his brother, Liam, and how they coped with the loss of Jennifer when the couple were firmly in the public eye.
