Two thirds of Britons believe the Duke of York should be stripped of his remaining royal titles, according to a new poll.

Research by YouGov found that 67 per cent of the public would back the removal of Andrew’s York dukedom, as well as his princely title.

An unflattering biography of the disgraced duke by Andrew Lownie in August delved into the private life of the King’s younger brother, depicting him as sex-obsessed, a “useful idiot” and easy prey for disgraced financier Jeffrey Epstein.

It includes allegations of a punch-up with Andrew’s nephew, Prince Harry, and rude treatment of royal staff – including calling one long-standing royal employee a “f—ing imbecile” for failing to give the Queen Mother her full title.

Some 13 per cent of those survey opposed removing Andrew’s titles and 21 per cent were unsure.

Three years ago, 62 per cent believed Prince Andrew should have his York title removed, with the current 67 per cent in-favour figure representing a jump of five percentage points.

Earlier this week, another YouGov survey found that just 5 per cent of those asked have a positive view of Andrew. He languishes at the bottom of the royal favourability tables, beneath the Duchess of Sussex (20 per cent positive rating) and the Duke of Sussex (28 per cent).

Legislation would be required for Parliament to prevent Andrew continuing as the Duke of York, while his birthright to be a prince, as the son of a monarch, could be changed in a Letters Patent issued by the King.

The duke stopped using his style of his royal highness following his disastrous Newsnight interview, but it could be removed entirely by a Letters Patent.

Andrew stepped away from his public role in 2019 amid the furore over his friendship with convicted billionaire paedophile Epstein.

He later paid millions to settle a civil sexual assault case with Virginia Giuffre, who was trafficked by Epstein as a teenager.

Andrew claims never to have met Giuffre, despite a photograph of them together. He denies all of her allegations.
