Prince Andrew has been given a lifeline in his Royal Lodge battle with his brother, King Charles, after allegedly receiving a sum of money from a mystery donor

Multiple royal experts claimed Prince Andrew is "digging his heels," refusing to downsize and move into Prince Harry and Meghan Markle's former U.K. home, Frogmore Cottage.

One author says there's a possibility the Royal Collection Trust could "start taking the paintings and some of the furniture away."

King Charles is increasing the stakes in his ongoing housing drama with Prince Andrew. The brothers have been embroiled in a years-long battle over Andrew’s residence at Royal Lodge, with the monarch cutting off his younger brother’s allowance and private security as an “ultimatum” to get his brother to move into a smaller residence.

King Charles is reportedly considering taking a drastic measure to try and force his brother Prince Andrew out of the 30-room Royal Lodge.
