Season 4

Uncovering the secret stories of love and marriage from within palaces walls, beginning with the strange mystery of Squidgygate and Princess Diana's intimate Sandringham phone conversations with her 'friend', James Gilbey.

Stories of palace private life - and the moments the royals wish were private - beginning with the royal family's race to be by Elizabeth II's side in her final moments at Balmoral. The programme forensically examines that day and uncovers how the deep family rift between Prince Harry and the rest potentially caused a tragic delay. Kate Williams shines a light on some of the most remarkable private tales from palace history, including the messy end of William the Conqueror's life when he was buried by a band of hapless monks.

This time, we uncover secret stories of palace scandal, as Diana confesses all to one of her closest member of staff, King Charles tries to move out his scandal-hit brother and we reveal the shocking link between Queen Victoria's favourite lapdog and a palace massacre.

We uncover secret stories of palace duty; including Queen Elizabeth II’s final balcony appearance; how not to look after the Crown Jewels; and Kate’s first palace assignment abroad.

Uncovering the secrets of Palace entertaining, from Wayne Sleep teaching Princess Diana how to dance, to the Buckingham Palace party that almost went up in flames.
