King Charles continues to undertake his royal duties despite undergoing treatment for cancer. The monarch, who assumed the throne when his mother, Queen Elizabeth II, passed away in 2022, has had a very rocky start to his reign, not only because of the many health issues that have struck the Royal Family, but also because of the ongoing strife involving his son, Prince Harry.

While Charles, Camilla, Prince William, and Kate Middleton are often the most public members of the Royal Family, they aren’t the only ones. Charles’ sister, Princess Anne, also reportedly plays a crucial part within the Firm, aiding the king in any way she can.

While Charles and Anne might have different opinions about the direction the Royal Family will take moving forward, their love and support for one another will never fade. Recently, Charles was said to have even started crying when his sister gave him an update on her royal future.

King Charles and Princess Anne have enjoyed a close bond their entire lives. With only a 21-month age difference, the brother-sister duo grew up at Buckingham Palace with their parents, Queen Elizabeth II and Prince Philip, and have been there one another since childhood.

When Charles took the throne in 2022, Anne was ready to support her brother, and it appears she has no plans to retire. Last year she was in an accident that left her in hospital with a concussion, but the 74-year-old pressed on with her royal duties as soon as she had made a recovery.

Charles and Anne have performed many royal engagements together over the years. Anne famously has a nickname for her brother, too, as she once was heard calling Charles an “old bean.”

Meanwhile, Anne is known to be one of – if not the – hardest-working members of the Royal Family, and was branded a “workhorse” by royal correspondents Roya Nikkhah and Kate Mansey of The Times. The princess recently visited South Africa as part of her royal duties, where she reflected on the accident she suffered last year.
