King Charles was pictured leaving Sandringham Church on Sunday morning.
The 77-year-old monarch emerged from the 16th-century church of St. Mary Magdalene in a beige coat.
Accompanied by a clergyman, he offered little more than a tense expression as he made his way through supporters following the service.
The appearance comes just days after Andrew Mountbatten-Windsor was arrested on suspicion of misconduct in public office and questioned for 11 hours at Aylsham Police Investigation Centre.
Within hours of his brother’s arrest, the king issued a rare and forceful statement, pledging his “unconditional support and cooperation” to investigators.
the mail Sunday reports that Charles was alerted as early as 2019 about concerns about Andrew’s business connections.
According to leaked correspondence, a whistleblower contacted the then Prince of Wales through royal lawyers Farrer & Co.
They warned that the Royal Family’s reputation was being exploited through financial links to controversial financier David Rowland.
In one message, the complainant claimed that Andrew seemed to prioritize his association with Rowland over family considerations.
A second email, reportedly sent directly to Rowland and copied to senior palace officials including Clive Alderton and the queen’s late lawyer Mark Bridges, alleged misuse of royal connections.
