In this lively and colourful history, royal expert Tom Quinn goes behind palace doors to give a compelling glimpse of Britain's royals, ancient and modern. From medieval times, when the Groom of the Stool oversaw the monarch's lavatorial exploits, below-stairs staff have always had a unique insight into the lives of their royal masters.

Now fully updated with a scandalous new chapter revealing how the former Prince Andrew's life has changed since being cast out by the royal family, Yes, Ma'am is the ultimate insight into what really makes the royal family tick - after all, who better to ask than their army of servants and staff, past and present?
