King Charles III allegedly has warned Prince Andrew of serious consequences if he does not move out of Royal Lodge and into Prince Harry and Meghan Markle's former U.K. home, according to a new report.

It's been over a year since reports first surfaced that the British monarch wants to evict his disgraced younger brother from the 30-room, $37 million residence where he has lived since 2004, but the Duke of York continues to stay put.

Prince Andrew's refusal to leave the property and move into Frogmore Cottage has left King Charles so frustrated that he's allegedly threatened to cut ties completely with him, The Times U.K. reported, citing an unnamed "friend" of the monarch.

King Charles could restrict funds from Prince Andrew -- who is no longer a working royal and appears to have no source of income -- if he continues to refuse to budge, the source suggested.

"Unfortunately, if Andrew refuses to leave within a reasonable time frame, then the King may be forced to reassess the whole package of support he provides, and the duke would be required to fund the lion's share of his security, accommodation, and lifestyle costs all on his own -- which, given the sums involved, is highly unlikely to be possible in the long term," the royal insider told the outlet.

The source added that while King Charles is "mindful" of his brother's "well-being," there are "limits" to his "patience and tolerance."

"As things stand, life at Royal Lodge is set to become increasingly cold and uncomfortable for the duke," the so-called friend claimed.

Prince Andrew reportedly signed a 75-year lease agreement for Royal Lodge in 2003, and the deal included him paying for the upkeep of the property.

He reportedly spent millions renovating Royal Lodge before stepping back from royal duties in 2019 over his ties to convicted sex offender Jeffrey Epstein.

Following the scandal, however, the Duke of York reportedly stopped receiving his annual allowance of around £250,000 ($314,000), Us Weekly reported.

According to the outlet, Prince Andrew allegedly has been unable to keep up with payments to maintain the 19th century, Grade II listed mansion, which requires around $500,000 per year in upkeep.

Photos recently obtained by the Daily Mail of Royal Lodge showed paint peeling and cracks forming in the walls, among other signs of disrepair.

King Charles is said to have offered Prince Andrew Frogmore Cottage, Prince Harry and Markle's former home, but the Duke of York reportedly thought it would be too big of a downgrade, according to Us Weekly.

Royal biographer Christopher Andersen alleged to Fox News Digital that Charles had wanted Prince Andrew to leave Royal Lodge even before their mother Queen Elizabeth II's death in 2022.

"After he became king, Charles began pressuring Andrew to move into more modest quarters at Windsor, but Andrew dug in," the "King" author said, noting that "no one" among the Duke of York's many wealthy friends and associates has "stepped up" to help him.

Andersen added, "Now that he's battling cancer, the king doesn't have the stomach for another skirmish with his brother. It seems inevitable, however, that Andrew will eventually be tossed out on his ear."
