The battle between King Charles and Prince Andrew over the Duke of York's home, the Royal Lodge, has been dragging on for years at this point, but this week one royal author pointed out that the historic estate has a significant number of "treasures" that the royal collection may want back.

Appeared in the Daily Mail's Palace Confidential YouTube show, Robert Hardman, author of King Charles III: The New King. New court. Inside Story, historically said, the Royal Lodge was "a house that always belonged to someone who performed official duties on behalf of the country."."

Because Andrew is no longer making royal engagements on behalf of the king," it wonders, in a place where he has been the home of the sovereign Hardman for years.

Prince Andrew will be sworn in in 2019 after facing widespread public backlash amid allegations of sexual assault and the infamous BBC Newsnight interview. King Charles, who no longer financially supports his brother or his safety at the Royal Lodge, has called on the Duke of York to move into a small house, but Andrew has kept digging his heels.

"It is the property of the crown, and the property of the crown will ultimately answer the government," the author said, pointing out that it is not the king's call on whether or not to abandon the brothers in the end. But Hardman said, "We don't want to see it go into disrepair" — and according to many reports, the Royal Lodge does exactly that.

The crumbling house is in need of major repairs, but the Duke of York has reportedly recently donated money to carry out renovations worth about3320,000 to Princess Beatrice's real estate developer husband, Edoardo Mapelli Mozzi, who is reportedly supporting extensive efforts. It's a good idea.

Hardman shared that "the Royal Collection, which owns quite a lot of treasures there, may say, 'We can't be sure this place is safe anymore,' and they will start taking away some of the paintings and furniture."

George 6, Queen Elizabeth, and Queen's mother lived in the Royal Lodge with Princess Elizabeth (later Queen Elizabeth 2) and Princess Margaret, but the Queen's mother returned to the Royal Lodge after her husband died and lived there until his death in 2002. The house, of course, features a number of precious antiques and paintings, but according to the Daily Mail, it is also said to be "cluttered with a teapot of novelty" that Prince Andrew's ex-wife, Sarah Ferguson, has collected over the years.

At the end of the day, Hardman noted that it would cost the Duke of York "millions of pounds a year" to stay at the Royal Lodge. "How long can he continue to plunder his savings to pay these very substantial bills?""The author wondered. "Let's see."
