As Queen Elizabeth reaches the historic milestone of 70 years on the throne, her upcoming platinum jubilee was expected to be a highlight of her life. A time when her decades of nearly flawless service to the Crown would be celebrated across Britain and the Commonwealth.

Instead, she鈥檚 had to remove HRH and military titles from her son Prince Andrew, she鈥檚 living in the wake of Harry and Meghan leaving the family, and she saw the first Caribbean country in her Commonwealth officially split from the Crown.

It鈥檚 a tumultuous time in the House of Windsor; one that鈥檚 raising concerns about the future of the monarchy.

Throughout Queen Elizabeth鈥檚 reign, royal scandals have come and gone. But none have landed in a U.S. courtroom. Prince Andrew, known as the Queen鈥檚 favourite son, is facing accusations of sexual abuse by an American woman when she was 17 years old.

The royal, ninth in line to the throne, no longer has 鈥淗is Royal Highness鈥 before his name, or any military titles after it 鈥 a move the Queen ordered after more than 150 veterans wrote a letter calling for it.

Royal biographer calls it a mess.

鈥淎ndrew has always been quite an irrelevant figure within the royal family. But when you get veterans calling for his removal from his position as head of various regiments, then that becomes really damaging to the monarchy,鈥 Junor told W5.

Royal biographer Penny JunorAndrew claims to never have met his accuser. But a photo shows him with his arm around her. Andrew also tried to distance himself from Jeffrey Epstein, the man who allegedly introduced them. But another photo shows the prince walking and chatting with him. By then, Epstein was a convicted pedophile.

鈥淚 think he's actually fundamentally just very stupid,鈥 Junor said of Andrew. 鈥淗e has no, no awareness.鈥

Prince Harry was another favourite of the Queen鈥檚. He reportedly often made his grandmother laugh. Now, the youngest son of Prince Charles is on the other side of the ocean, physically and officially separated from the Royal Family.

Junor believes Harry鈥檚 marriage to a mixed-race American actress could鈥檝e actually helped the country. 鈥淚t could have been so healing in terms of racial tensions in Britain,鈥 she said. Instead, Meghan spoke about racism inside what she referred to as 鈥淭he Firm.鈥

As all of this dramatic family distancing unfolds inside the House of Windsor, there are signs of fracture in the Queen鈥檚 Commonwealth as well. Barbados, tied to the British Crown for nearly 400 years, has now officially become a republic, an independent country without a queen as head of state. Jamaica is looking at that possibility as well. And Canada? Polls here show support for the monarchy is dwindling to the lowest ever seen.

The Queen called 1992 her 鈥渁nnus horribilis鈥 (horrible year), when three of her children started steps towards divorce. But with her House of Windsor publicly shaken to the core, what must she be thinking now?

Correction:

A previous version of this story stated that Prince Andrew is the Queen's youngest son. Prince Andrew is the second-youngest son, as he is older than Prince Edward.
