Series 1, Episode 10: What if the monarch's eldest daughters - instead of their sons - had been crowned throughout history? This week on The Royal Beat: Back in Time we ask exactly that. Kate Thornton is joined by historians Dr Fern Riddell, Kate McCaffrey and author of 'Regina, The Queens Who Could Have Been' Emily Murdoch Perkins. From the wildly independent daughter of a medieval King to the woman who launched the Tudor dynasty, and also a Victorian Princess who could have changed the fate of Europe, our experts uncover the lives of these royal women who were never crowned.
