Forensic archaeologist Professor Margaret Cox explains why she plans to set up a specialist centre for investigating genocide.
An expert on Channel 4's 'Time Team', Margaret has also worked with the Ministry of Defence to identify the bodies of soldiers killed in World War One, and two years ago went to Kosovo to search for a mass grave.
She tells Sheila what she's learned from these experiences, and whether 'Time Team' has sparked a new interest in archaeology.
