King Charles tries to put on a brave face as he is pictured leaving church today amid Andrew scandal

King Charles was spotted putting on a brave face as he left church on Sunday as his brother Andrew Mountbatten-Windsor scandal continues to shake the Royal Family.

The monarch looked glum as she left St Mary Magdalene Church in Sandringham after a service this morning.

Charles, 77, was wearing a beige coat, blue shirt and navy-red tie and was accompanied by a priest from the 16th-century church.

He appeared frowning as he left the post, which came just three days after his brother was sensationally arrested on suspicion of misconduct in public office and held for 11 hours at Aylsham Police Investigation Centre.

Her appearance comes as she faces calls to reveal how much she knew about Andrew’s alleged misconduct before his arrest.

The King made an unprecedented statement just hours after his arrest on Thursday, confirming his ‘wholehearted support and co-operation’ with the investigation into Andrew; It is understood that Buckingham Palace did not know that the former Duke of York would be arrested.

But the Mail on Sunday revealed the King was warned as long ago as 2019 that the Royal Family’s name was being ‘exploited’ by Andrew’s business associations.

In a bombshell email, an informant is understood to have told the Palace that the former Duke had secret financial links with controversial millionaire financier David Rowland, who exploited his royal connections.

Messages seen by this newspaper also show Andrew allowing Mr Rowland to effectively participate in his official duties.

Charles, 77, grimaced as he left church on Sunday as his brother Andrew Mountbatten-Windsor scandal continued to rock the Royal Family.

He appeared frowning as he left the army just three days after his brother’s sensational arrest.

The cache of emails, triggered by Andrew’s links to Jeffrey Epstein and allegations that he passed confidential and potentially sensitive documents to the convicted pedophile, threatens to draw Charles further into crisis.

Andrew once told Epstein that Mr Rowland was a ‘trustworthy money man’. The banker and his son, Jonathan, joined Andrew on trips in his official capacity as a taxpayer-funded trade ambassador between 2001 and 2011, visiting places such as China and former Soviet states.

Mr Rowland once gave £40,000 to Andrew’s ex-wife Sarah Ferguson to help clear debts, and in 2017 she paid Andrew a £1.5 million loan.

In August 2019, a tipster with detailed knowledge of Andrew’s business dealings with Mr Rowland sent an email, through royal lawyers Farrer & Co, to Charles, then Prince of Wales, warning that ‘David Rowland was abusing the Royal Family’.

The letter said: ‘The actions of His Royal Highness the Duke of York show that His Royal Highness views his relationship with David Rowland as more important than that of his family.’

The tipster then sent a second email to Mr Rowland, which included copies of Charles’ private secretary Clive Alderton and the late Queen’s lawyer Mark Bridges at Farrer & Co.

The message said: ‘The evidence provided clearly proves that you are giving the Royal Family a bad name.’

King Charles on Thursday said he would give police access to all files and records needed for any investigation into his disgraced brother.

The arrest comes after Thames Valley Police said it was ‘assessing’ reports that Andrew shared secret trading reports and investment opportunities with pedophile Jeffrey Epstein in 2010 and 2011, when he was Britain’s special trade envoy to Asia.

Andrew was photographed leaving Aylsham Police Station in Norfolk following his arrest on Thursday

Andrew was questioned for 11 hours immediately following his arrest and was filmed trying to hide from cameras in a Range Rover as he left Aylsham Police Investigation Centre.

He was taken from Wood Farm on the royal estate of Sandringham in Norfolk after being evicted by King Charles from his residence Royal Lodge in Windsor earlier this month.

Police have searched Wood Farm and are searching the seven-bedroom Royal Lodge mansion as part of the investigation.

Police now have wide leeway to expand their investigation and will “follow the evidence” if they come across another crime while combing through the former prince’s files and belongings, The Observer reported.

Andrew, who was kicked out of the Royal Lodge earlier this month, reportedly shouted: ‘I’m the Queen’s second son, you can’t do this to me’ when he was forced out of the mansion.

The former Duke of York left the 30-room Windsor mansion, to which he had paid ‘pepper rent’ for decades, under cover of darkness earlier this month.

King Charles is understood to be increasingly concerned about allegations against his brother, who was arrested this week on suspicion of misconduct in public office.

But Andrew reportedly does not want to leave the property and move to Wood Farm on the Sandringham Estate in Norfolk, where he currently resides.

Days earlier, he had been photographed cheerfully greeting the crowd as he rode his horse; Sources said these images were likely the last straw for royal courtiers who wanted to expel him from the Royal Lodge.

His reluctance to move house was revealed as a senior MP called for Andrew to be investigated for treason over accusations he passed confidential information to Epstein.

Former Security Minister Tom Tugendhat is demanding the establishment of a special committee with the power to call witnesses and request documents.

The last person to be convicted of treason in the UK was Jaswant Singh Chail, who entered Windsor Castle with a crossbow on Christmas Day 2021 to kill the late Queen.
