Last week, the Duke of York reached an out-of-court settlement with Ms Giuffre, ending their highly-publicised legal battle. Ms Giuffre began suing the prince, 61, through a New York court last year for “substantial” damages after claiming that he sexually assaulted her.
The prince always vehemently denied her claims – insisting that he had “no recollection” of ever meeting Ms Giuffre after she had been groomed and sex trafficked by paedophile financier Jeffrey Epstein.
The exact details of the settlement – which included “substantial” payments to Ms Giuffre and her victim’s of abuse charity – has not been released.
But observers have claimed that it is somewhere between £7million and £12million – with the Queen said to be contributing towards some of the final bill.
How much, if any, of it directly or indirectly comes from the taxpayer is of much debate.

Some of the cash could come from Andrew selling the Swiss chalet that he owns with his ex-wife Sarah Ferguson.
The prince also receives an armed forces pension – thought to be about £20,000 a year – but that would not go far towards settling the debt.
Whether he has any savings from his time as a “working royal” when he earned about £250,000 per year remains a mystery.
Royal finance expert David McClure told the BBC also said that if the sum was “of the order” of £5million or above he would need the Queen’s help.
He added: “I don’t think he has that money. And it’s more than likely the Queen will fork out some money.”
If this money came from the Queen’s private estate of the Sovereign Grant – set at £86.3million last year – is unknown.
The Queen also receives private income from the Queen’s Privy Purse which is generated from a private estate known as the Duchy of Lancaster.
It covers over 18,000 hectares of land and usually makes a profit of about £20million each year.
The Queen also has an income through properties such as Sandringham and Balmoral, which she owns privately.
