Prince Andrew of Britain on Friday renounced his title of Duke of York and other honours after being increasingly embroiled in scandals around his ties to US sex offender Jeffrey Epstein.

"I will... no longer use my title or the honours which have been conferred upon me," Andrew, 65, said in a statement.

He said his decision came after discussions with his brother, King Charles III, and his own "immediate and wider family".

He again denied all allegations, but said "we have concluded the continued accusations about me distract from the work of His Majesty and the Royal Family".

Andrew, who stepped back from public life in 2019, will remain a prince, as he is the second son of the late Queen Elizabeth II.

But he will no longer hold the title of Duke of York that she had conferred on him.

His ex-wife Sarah Ferguson will also no longer use the title of Duchess of York, though his daughters Beatrice and Eugenie remain princesses.

The bombshell announcement came after new allegations emerged this week in the posthumous memoir of Virginia Giuffre, the woman at the centre of the Epstein scandal.

She wrote that Andrew had behaved as if having sex with her was his "birthright", saying she had sex with Andrew on three separate occasions including when she was under 18.

Giuffre rose to public prominence after alleging the disgraced US financier Epstein used her as a sex slave and that Andrew had assaulted her.

Andrew has repeatedly denied Giuffre's accusations and avoided trial by paying a multimillion-dollar settlement. (AFP)
