William, Kate, Harry and Meghan during a service for the late Queen at Westminster Hall

The Firm awaited the arrival of the coffin before an informal supper, throwing together the two warring couples. However according to the new biography Charles II. New King. New Court. The Inside Story by author Robert Hardman, William and Kate offered a small olive branch, which would have gained the approval of Elizabeth II.

He explains: “Inside the palace, all members of the Royal Family were there to welcome the Queen back to royal headquarters for the last time, followed by an informal supper. Afterwards, the Prince and Princess of Wales suggested that the Duke and Duchess of Sussex should attach their car to their police escort for the journey back to Windsor since they were all going the same way. It was only a small gesture (they would not be sharing a car) and nowhere near any sort of reconciliation. However, the late Queen would have approved.”

The death of the late Queen came just months before Harry and Meghan released their controversial Netflix docuseries where they dropped a series of bombshells about life in the Firm. Both William and King Charles came under fire in the series, with William accused of “screaming and shouting” and King Charles of ‘lying’ at a high-profile summit.

And according to the book friends of the Royal Family believed it was clear he was talking about William and Kate. One tells the author in the book: “On top of all the other breaches of trust, here was Harry making a blatant attack on Catherine. For William, this was the lowest of the low.”

Several weeks later, when Harry’s memoir Spare was published, he also didn’t hold back when dishing about Kate and revealed private details about a falling out between her and Meghan in his memoir Spare. He also described how Kate allegedly ‘grimaced’ when Meghan borrowed her lipgloss and how the women had a disagreement after the Duchess of Sussex said William’s wife had “baby brain” after Prince Louis was born.
