Prince Andrew is to lose his 'prince' title and leave his Windsor mansion, Royal Lodge, following weeks of intense scrutiny over his links to convicted sex offender Jeffrey Epstein.
In a statement on Thursday night, Buckingham Palace said the King's brother will now be known as Andrew Mountbatten Windsor.
Andrew gave up his other royal titles earlier this month, including the Duke of York, after facing more questions about his private life.
In a posthumous memoir published earlier this month, Virginia Giuffre repeated allegations that, as a teenager, she had sex with Prince Andrew on three separate occasions. Andrew has always denied the claims.
Reacting to the latest developments, Ms Giuffre's family said she "brought down a British prince with her truth and extraordinary courage". Giuffre took her own life earlier this year.
