CAMPAIGNERS warned today that stripping Andrew Windsor of his royal titles is not enough and that he must face a criminal investigation.

Buckingham Palace announced on Thursday that the King’s brother will be formally stripped of his prince title and have to leave the Royal Lodge mansion, where he has been living rent-free for 20 years. He will now be known as Andrew Mountbatten Windsor.

The disgraced royal, whose ties to convicted paedophile Jeffrey Epstein led to his downfall, will instead move to a property on the King’s lavish Sandringham estate.

Andrew had long faced allegations that he sexually abused Virginia Giuffre, who was trafficked by Epstein.

New details emerged last month in Ms Giuffre’s memoir, published posthumously, in which she said that Mr Windsor had sex with her aged 17 like it was his “birthright” and partook in an “orgy” with Epstein and eight girls who “all appeared to be under the age of 18.”

The Mail also published claims that Andrew tried to get his Metropolitan Police bodyguard to dig up dirt for a smear campaign against her.

Andrew paid a reported £12 million to settle a civil sex case with Ms Giuffre in 2022, despite claiming he had never met her.

Buckingham Palace said that the King had “initiated a formal process to remove the style, titles and honours” of the royal.

It added that “formal notice has now been served to surrender the lease” on his residence at the 30-room Royal Lodge, although it is understood that Andrew will not relocate to Sandringham until after Christmas.

Lauding the decision, the family of Ms Giuffre, who died by suicide in April, said she “brought down a British prince with her truth and extraordinary courage.”

Andrew will also formally lose the title as the Duke of York, the style His Royal Highness, and has already been struck from the official roll of the peerage.

But Graham Smith, from anti-monarchy group Republic, said: “Removing Andrew’s title of ‘Prince’ isn’t enough. It’s that simple.

“This is a man who has been accused of sexual assault and corruption. He should be questioned and investigated by the police. This is about justice, not titles.”

Republic has already instructed lawyers to consider a private prosecution against the royal after raising thousands in crowdfunded legal fees.

Mr Smith added: “How is moving from one mansion to another in any way a punishment?

“This is an insult to sexual abuse victims and an insult to the public.”

Writing on X, independent MP Zarah Sultana said the title removals were a “good start.”

“Now let’s do the rest of them and abolish the monarchy,” she added.

Today, Times Radio asked trade minister Chris Bryant why Lord Mandelson kept his peerage despite having links to Epstein.

“I don’t think that just having known somebody is the issue,” he said.

When probed again why the former US ambassador remained a Lord, he said: “Personally I’ve always been in favour of an elected second chamber.”
