That's why the claims this week of corruption at the very top of Charles' charitable network are bound to be of concern to Buckingham Palace.

The chief executive of The Prince's Foundation -- the umbrella group for Charles' charitable organizations -- temporarily stepped down amid claims that he helped secure an honorary title for a major donor.

According to an investigation by the Sunday Times, Michael Fawcett helped nominate Saudi businessman Mahfouz Marei Mubarak bin Mahfouz for a coveted CBE. It was reportedly in exchange for substantial charitable contributions. CNN has reached out for comment from Mahfouz and Fawcett.

Charles himself is not under any scrutiny and a spokesman for the prince told CNN he has "no knowledge" of the alleged scandal. Nonetheless, the association is embarrassing.

The Prince's Foundation is now investigating and, more significantly, the Metropolitan Police are said to be looking into a complaint made by the anti-monarchy group Republic.

Charles doesn't just provide advice to his causes, he's also their key fundraiser. Staff will also tell you that he raises more than £100 million ($139 million) a year for charity through a packed diary of engagements.

This work is separate from his constitutional role representing the Queen at official events, which are paid for and supported by the British government.

That separation is deliberate, to avoid any suggestion of a conflict of interest or abuse of power. His charities are operated outside his main office at Clarence House, and that's something royal sources have emphasized this week while battling the scandal.

Michael Fawcett, former valet to Prince Charles and current chief executive of the Prince's Foundation (L), accompanies Prince Charles at Ascot Racecourse in England on November 23, 2018.

Charles has spent years trying to rid himself of the nickname "the meddling prince" -- coined by some British tabloids -- and prove his impartiality as a future head of state. With the UK being a constitutional monarchy, royals are meant to remain neutral and avoid expressing their personal views on policy.

Charles has come under fire from time to time following interventions on subjects close to his heart. In 2015, 27 letters written by the prince were released under the Freedom of Information Act and showed him lobbying government departments on a number of subjects, such as farmer subsidies and promoting
British produce. He addressed being an outspoken heir in a 2018 documentary, saying he had "tried to make sure whatever I've done has been nonparty political" but acknowledged that he will have to act differently as sovereign.

This recent episode is particularly difficult for Charles, as Fawcett is -- without doubt -- his longest-serving and most loyal aide, having worked his way up from a valet position in the royal household to CEO of his foundation. It's also difficult personally, because Charles once described Fawcett as "indispensable."

Charles has not been accused of any kind of wrongdoing but as direct successor to the throne a certain level of decorum is expected of him. A continued association with a right-hand man -- who left his valet role in 2003 after he was cleared of selling unwanted royal gifts and taking a cut -- could ultimately taint Charles' reputation. Both will be hoping the investigations are concluded swiftly.

WHAT ELSE IS HAPPENING?

Queen Elizabeth supports Black Lives Matter movement, says aide.

Queen Elizabeth II and the royal family back the Black Lives Matter (BLM) anti-racist movement, according to a senior representative. UK broadcaster Channel 4 asked Ken Olisa, the first black Lord-Lieutenant for London, whether the royal family supports BLM. "The answer is easily yes," he said, adding that the issue of race is a "hot conversation topic" in the royal household. The royal family's attitude to race has been in the spotlight recently following allegations of racism from Prince Harry and Meghan, Duchess of Sussex, and the revelation that ethnic minority immigrants and foreigners were banned from clerical positions at Buckingham Palace until at least the late 1960s.

The Cambridges' foundation puts diversity front and center.

William and Kate's Royal Foundation is stepping up its approach to diversity, it said in its annual report. In its 2020 Trustees' and Auditor's report, the charitable organization reiterated its commitment to equality and diversity and "to ensuring a positive, safe and respectful environment which promotes the wellbeing and dignity of its employees, applicants, partners, suppliers and those whose interests it represents." The 44-page document highlighted that it "also has been working since early 2020 to place its approach to diversity -- as an employer, partner, and designer of charitable initiatives -- at the centre of its overall strategy." Additionally, a "particular focus" has been placed on improving diversity among its board. It stated that formal diversity targets would be "considered, monitored, and reported on," after previously not being set. The report emphasizing a focus on diversity and inclusion in the past year comes after the Duke and Duchess of Sussex suggested in their interview with Oprah Winfrey that there was a culture of institutional racism in the monarchy and among family members. The family responded by saying they were taking the issues raised "very seriously" but would be addressing them privately.

Buckingham Palace acknowledged more work was needed to drive diversity within the royal household in its own annual financial report released in June.

Harry praises military charity expedition.

The Duke of Sussex has wished "good luck and good weather" upon a six-man team preparing for a 249-mile fundraising trek, after the Walking With The Wounded veterans charity announced its twice-delayed Grenadier Walk of Oman expedition would be "reimagined" in the UK. Harry, who has been expedition patron for a number of years, said: "The team at Walking With The Wounded understand that it's not about where you walk -- it's about walking together with a common purpose and shared mission. These men and women know what service is, they've seen and overcome adversity, and they won't let obstacles get in their way. They are paragons of inspiration for communities everywhere. We wish them good luck and good weather." The charity's CEO, Fergus Williams, said the decision to proceed with the venture in the UK was the result of continued uncertainty around the pandemic and travel restrictions. Set to start on October 10 at the Omani embassy in London, the team will walk the Thames Path trail and take on Pen-Y-Fan, the highest peak in the Brecon Beacons National Park in Wales.

William is back to work after his summer vacation.

Prince William speaks with Royal National Lifeboat Institution crew in London on September 9.

The Duke of Cambridge is returning to his royal duties as the summer holidays come to an end. On Thursday, he visited a fire station in south London to mark Emergency Services Day, where he met emergency responders and members of the public who have received life-saving support. Following the engagement, he returned to Kensington Palace to host a meeting on suicide prevention within the emergency services community. The event with frontline response workers came a day before World Suicide Prevention Day on Friday. As a former Air Ambulance pilot and RAF Search and Rescue pilot, supporting the mental health and well-being of the emergency services community is a subject close to his heart.
