Prince Andrew has been stripped of his "prince" title and will leave his Windsor mansion, Royal Lodge, Buckingham Palace announced on Thursday.
The King has "initiated a formal process" to remove his titles, it said, and Andrew now be known as Andrew Mountbatten Windsor.
Andrew, 65 - the King's younger brother - has continued to face more questions about his private life in recent months.
His links to paedophile financier Jeffrey Epstein have caused problems for the Royal Family. The prince, who relinquished his titles earlier this month, has always strongly denied any wrongdoing.
"His Majesty has today initiated a formal process to remove the Style, Titles and Honours of Prince Andrew," Buckingham Palace said in a statement on Thursday evening.
