In the course of a public appearance to a cathedral in Staffordshire on the start of the week, King Charles was heckled by a protester who questioned him about his brother's links with convicted sex offender Epstein.
The man demanded to know how long the King had been known about his sibling's association with Jeffrey Epstein, and also questioned whether he had instructed the authorities to "cover up" for Andrew.
Amid the heckling, there were large groups of supporters and cheers for the monarch, who was in the region for an ceremony.
The Duke of York's links with Jeffrey Epstein have been under close examination in recent weeks. The prince, who relinquished his royal duties earlier this month, has repeatedly denied any misconduct.
"How long have you been aware about Prince Andrew and Epstein? Have you asked the police to conceal for Andrew?"
The monarch ignored the questions but continued meeting fans, some of whom shouted "God Save The King". One supporter can be overheard requesting him for a embrace.
Another woman outside the cathedral was also heard telling the protester to "go away" and to "shut up".
The controversy over Prince Andrew's links to Epstein has been brought back into focus by misconduct claims repeated in Ms. Giuffre's posthumously-published book.
In the memoir, the accuser alleges she had sexual encounters with the royal on three separate occasions, including once with Jeffrey Epstein and "several other minors"
Prince Andrew, who agreed to a out-of-court agreement with Ms Giuffre in 2022, has repeatedly denied any misconduct. In 2019, he told BBC Newsnight he did not remember meeting Ms Giuffre "ever", and that they "did not have any sort of sexual contact."
But recently, fresh questions have been raised about how he is able to finance his lifestyle despite not being a working royal.
The disclosure that he has only ever paid a token annual rent on his Windsor mansion has heightened the scrutiny over his living arrangements - even though he made significant contributions up front, including for renovations.
The Liberal Democrats said he should be called in before MPs to give evidence about his lease of his residence.
But last Thursday, the authorities declined to give parliamentarians time to discuss the royal's status or his residence, despite increasing calls for scrutiny.
The royal household has not commented on whether Prince Andrew might move out of his home - or where he might reside.
