In the course of a engagement 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 connections with convicted sex offender Epstein.
The man asked how long the monarch had been aware about his sibling's relationship with Jeffrey Epstein, and also raised doubts about whether he had instructed the authorities to "cover up" for Andrew.
Despite the heckling, there were large groups of fans and cheers for the King, who was in Staffordshire for an event.
Prince Andrew's connections with Epstein have been under intense scrutiny in the past few weeks. The royal, who gave up his titles earlier this month, has strongly denied any misconduct.
"How long have you known about Prince Andrew and Jeffrey Epstein? Did you request the police to cover up for him?"
The monarch ignored the questions but continued greeting fans, some of whom shouted "God Save The King". One supporter can be overheard asking him for a embrace.
A female bystander outside the venue was also heard telling the heckler to "leave" and to "be quiet".
The scandal over Prince Andrew's connections to Epstein has been reignited by misconduct allegations repeated in Virginia Giuffre's posthumously-published book.
In the publication, Ms Giuffre claims she had sex with the prince on multiple times, including once with Jeffrey Epstein and "eight other young girls"
Andrew, who reached a financial settlement with the plaintiff in recent years, has repeatedly denied any misconduct. In 2019, he told BBC Newsnight he did not remember meeting her "ever", and that they "did not have any sort of intimate relations."
But in recent times, fresh questions have been asked about how he is able to finance his lifestyle despite not being a active member of the royal family.
The disclosure that he has only ever paid a nominal fee on his Royal Lodge has intensified the scrutiny over his living arrangements - even though he made large payments up front, including for improvements.
The Liberal Democrats said he should be called in before members of parliament to give evidence about his rental agreement of his lodge.
But last Thursday, the authorities refused to give MPs time to discuss the royal's titles or his home, despite increasing calls for investigation.
Buckingham Palace has not issued a statement on whether Prince Andrew might relocate of his current residence - or where he might go.
