In the course of a engagement to Lichfield Cathedral on the start of the week, the King was heckled by a individual who asked him about Prince Andrew's links with disgraced financier Epstein.
The man inquired how long the monarch had been aware about his brother's association with Jeffrey Epstein, and also raised doubts about whether he had instructed the police to "cover up" for Andrew.
Amid the heckling, there were large groups of supporters and applause for the King, who was in the region for an engagement.
Prince Andrew's links with Epstein have been under renewed focus in recent weeks. The royal, who gave up his titles earlier this month, has categorically denied any wrongdoing.
"How long have you been aware about Prince Andrew and Epstein? Did you request the police to cover up for him?"
The monarch remained silent but continued greeting supporters, some of whom chanted "God Save The King". One fan can be heard asking him for a hug.
Another woman outside the cathedral was also observed telling the protester to "go away" and to "be quiet".
The scandal over Prince Andrew's links to Jeffrey Epstein has been reignited by sexual abuse allegations repeated in Ms. Giuffre's posthumously-published book.
In the memoir, the accuser claims she had sex with the prince on three separate occasions, including once with Jeffrey Epstein and "several other minors"
Prince Andrew, who agreed to a out-of-court agreement with the plaintiff in recent years, has repeatedly denied any misconduct. In 2019, he told a news program he did not recall meeting Ms Giuffre "at all", and that they "never had any sort of sexual contact."
But in recent times, fresh questions have been asked about how he is able to finance his lifestyle despite not being a working royal.
The revelation that he has only ever paid a token annual rent on his Royal Lodge has heightened the examination over his housing situation - 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 residence.
But last week, the government declined to give MPs time to discuss the royal's titles or his residence, despite increasing calls for investigation.
The royal household has not issued a statement on whether the Duke of York might move out of his current residence - or where he might go.
